Patrice Motsepe, president of the Confederation of African Football (CAF), has called for an immediate investigation into an incident at Olembe Stadium that resulted in the deaths of eight people, while he confirmed upcoming Africa Cup of Nations matches would be relocated.

Eight people died and a further 38 were injured after a stampede outside the stadium in Yaounde during Monday's match between tournament hosts Cameroon and Comoros.

CAF has started an investigation, while FIFA offered its condolences in a briefing on Tuesday.

In a media briefing, CAF president Motsepe confirmed the quarter-final tie due to be hosted at Olembe Stadium on Sunday, which will take place between the winner of Ivory Coast's clash with Egypt and the victor of Morocco v Malawi, would be moved to Yaounde's Ahmadou Ahidjo Stadium.

"I've been given lots of feedback and had lots of discussions until very early this morning," Motsepe said on Tuesday.

"The first thing that I’m going to ask the organising committees, the next match that's supposed to take place at the Olembe Stadium should not take place."

Motsepe also confirmed CAF had requested a report on the incident be completed by Friday.

"I spoke to the senior person in the government, and it's correct out of respect for our partners, to indicate that there must be an immediate committee set up to investigate what happened," he said.

"In that context, to find out who was supposed to do what and who did not perform their responsibilities.

"We want that report by Friday but as I said the game that is scheduled for Olembe Stadium on Sunday is not going to take place and it’s going to take place at Amadou. There will be other changes that will be made."

One of those other changes is reportedly moving Sunday's other quarter-final from Douala to Limbe.

A media release attributed to the Cameroon team was released on Tuesday, bearing the name of captain Vincent Aboubakar, was retweeted by the Cameroonian Football Federation (FECAFOOT) and appeared to question the behaviour of supporters in a statement that has received widespread criticism.

A statement attributed to the Cameroon national team has urged fans to remain "highly disciplined and responsible" after eight fans died in a stampede outside the Olembe Stadium during the match against Comoros.

Reports began circulating of a disturbance outside the ground as hosts Cameroon claimed a 2-1 last-16 win in the Africa Cup of Nations on Monday, with local media and the Associated Press suggesting at the time that several people had been killed.

Cameroon's Ministry of Communications then confirmed overnight that, after a "first assessment", eight people had lost their lives in the crush.

Another 38 people were injured, with seven of those in a serious condition.

The Confederation of African Football (CAF) has started an investigation, while FIFA offered its condolences in a briefing on Tuesday.

A media release attributed to the Cameroon team, bearing the name of captain Vincent Aboubakar, was retweeted by the Cameroonian Football Federation (FECAFOOT) and appeared to question the behaviour of supporters in a statement that has received widespread criticism.

"The Indomitable Lions and their entire staff deeply wail about the tragic incident that occurred at the Olembe Stadium on Monday, January 24, during the Cameroon vs Comoros match," the statement read.

"To the families of the victims, they extend their heart-felt condolences and wish a speedy recovery to the injured.

"The Indomitable Lions urge the football fans in Cameroon and Africa to be highly disciplined and responsible within and outside the stadiums so that football matches in general and the Africa Cup of Nations can remain festive moments.

"They also call for the preservation of security, brotherhood and shared happiness in the stadiums. On behalf of the Indomitable Lions, Vincent Aboubakar."

CAF has since announced the stadium will not be used for a quarter-final as initially planned following Monday's incident.

FIFA has sent its "deepest condolences" to the friends and families of the eight people who died in a stampede at the Olembe Stadium during Cameroon's Africa Cup of Nations win over Comoros.

Reports began circulating of a disturbance outside the ground as Cameroon claimed a 2-1 last-16 win on Monday, with local media and the Associated Press suggesting at the time that several people had been killed.

The Confederation of African Football (CAF) said it was aware of the incident and was gathering "more details" on what had transpired.

A statement released overnight by Cameroon's Ministry of Communications then confirmed that, after a "first assessment", eight people had lost their lives in the crush.

Another 38 people were injured, with seven of those in a serious condition.

The ministry did not immediately respond to Stats Perform's request for comment, but a widely reported statement read: "The Government of the Republic brings to the attention of the National and International Opinion that during the round-of-16 meeting which was played on Monday, January 24, 2022, between Indomitable Lions of Cameroon and the national team of the Union of Comoros, jostling occurred at the southern entrance to the Olembe Football Stadium.

"The first assessment of these jostling reports: eight dead; and 38 injured, including 31 light [injuries] and seven serious.

"The deceased were taken to the Yaounde Emergency Center for the appropriate formalities, and the injured were distributed to four health facilities in the city of Yaounde, where they were immediately taken care of, on very high instructions from the president of the republic, His Excellency Paul Biya."

World football's governing body expressed its sympathies with those affected by the tragedy soon after.

Its statement read: "FIFA sends its deepest condolences to the families and friends of the victims who lost their lives following the tragic incident that took place at Olembe Stadium during the Africa Cup of Nations fixture between Cameroon and Comoros.

"The thoughts and prayers of the global football community are with the victims, the ones who have been injured in this incident, and all the staff of both CAF and the Cameroonian Football Association (FECAFOOT) at this difficult moment."

CAF is attempting to gather information after a stampede during Cameroon's Africa Cup of Nations game against Comoros.

The incident took place at Olembe Stadium in Yaounde on Monday. No details of how many people were involved or how severely they were hurt were provided by CAF.

CAF's general secretary Veron Mosengo-Omba was sent to visit injured fans as the organisation attempts to gather more information on what occurred. 

The Associated Press reported multiple people had died.

A CAF statement read: "CAF is aware of the incident that took place at Olembe Stadium during the Africa Cup of Nations fixture between hosts Cameroon and Comoros tonight, 24 January 2022. 

"CAF is currently investigating the situation and trying to get more details on what transpired. We are in constant communication with Cameroon government and the Local Organizing Committee. 

"Tonight, the CAF president Dr Patrice Motsepe sent the General Secretary, Veron Mosengo-Omba to visit the supporters in hospital in Yaounde." 

Cameroon advanced to the quarter-finals by defeating 10-man Comoros 2-1. 

Comoros put in a tremendous performance despite being without a recognised goalkeeper and having 10 men for most of the game, as they succumbed to a narrow 2-1 loss to hosts Cameroon in the Africa Cup of Nations last 16. 

After booking their place in the knockouts with a famous win over Ghana, Comoros' fairytale quickly turned into a nightmare when a coronavirus outbreak in their camp left them without a keeper for the clash with Cameroon. 

Back-up option Ali Ahamada returned a negative result on Monday but was not authorised to play by CAF, meaning defender Chaker Alhadhur had to be deployed between the posts. 

The task facing Les Coelacantes was made even more daunting inside seven minutes when they lost their captain Nadjim Abdou, who was shown a straight red card after referee Bamlak Tessema Weyesa reviewed footage of his challenge on Moumi Ngamaleu.  

Cameroon struggled to test Alhadhur but finally broke through in the 29th minute when Karl Toko Ekambi dug out a shot that found the bottom-left corner.  

Andre Onana did well to keep out Ahmed Mogni and Mohamed Youssouf in quick succession as Comoros still showed plenty of adventure, with Alhadhur matching his counterpart by thwarting Vincent Aboubakar and Ngamaleu in a memorable double save after the restart.

Aboubakar sold Alhadhur a dummy to finally add to Cameroon's tally in the 70th minute, but Comoros rallied despite their numerical disadvantage and pulled one back through an incredible 35-yard free-kick from Youssouf M'Changama that sailed into the top-right corner. 

It was too little too late for Comoros, though, with their sensational maiden AFCON appearance brought to a harsh end, while Cameroon face Gambia next.

Comoros have been forced to name defender Chaker Alhadhur in goal for their Africa Cup of Nations last-16 clash with Cameroon.

The island nation are competing at their first AFCON and caused a major upset in getting out of the group stage, but their fairytale has swiftly turned into something of a nightmare.

An injury to first-choice goalkeeper Salim Ben Boina was followed up by back-ups Ali Ahamada and Moyadh Ousseini testing positive for COVID-19.

Comoros confirmed on Monday that Ahamada had returned a negative coronavirus test and rejoined the squad, sparking hope that Les Coelacantes might be able to face hosts Cameroon on something of a level playing field.

But reports soon began to emerge claiming the Confederation of African Football (CAF) was insisting Ahamada could not compete because he still needed to adhere to a five-day period of isolation.

CAF did not respond when contacted by Stats Perform, however Comoros' starting XI included Alhadhur as the team's starting goalkeeper, with the team's official Twitter account saying: "Following the decision of CAF not to authorize Ali Ahamada to play, it is Chaker Alhadhur who will be the goalkeeper of the team."

The 30-year-old, who represents French club Ajaccio, is nominally a left-back but will start arguably the biggest match of his career between the posts.

Cape Verde are plotting an Africa Cup of Nations upset when they do battle with Senegal in a round-of-16 derby and Morocco are strong favourites to beat Malawi on Tuesday.

Senegal won Group B despite scoring only one goal in three games, while Cape Verde qualified after finishing third in Group A.

Morocco topped Group C and will be expected to advance to the quarter-finals at the expense of a Malawi side that were third in Group B and will be playing their first AFCON knockout match.

Senegal v Cape Verde (16:00 GMT)

This will be the first Africa Cup of Nations clash between the two nations and Cape Verde will be playing only their second ever knockout match in the tournament.

The Blue Sharks were beaten 2-0 by Ghana at the quarter-final stage in 2013 and they will have to defy the odds at Kouekong Stadium to reach last eight once again.

Cape Verde coach Pedro Brito believes his players can spring a big surprise in Bafoussam.

He said: "We have worked hard in our training and facing a team like Senegal is an added motivation, because the match is like a derby.

"They have to respect us as a team the same way we respect them.

"The competition has seen a lot of surprises, and we hope to be the other team that will cause an upset as our mission is to win the game and move to the next round."

The Lions of Teranga have not been firing on all cylinders, but they are the only side in the tournament not to have conceded a goal.

The three sides to have faced Senegal have only been able to muster three shots on target between them, so Cape Verde must grasp any chances they are able to create.
 

One to watch: Idrissa Gueye (Senegal)

Paris Saint-Germain midfielder Gueye is a key man for Senegal, getting through so much work in the middle of the park.

Gueye has played a big part in his side being so solid and the industrious former Everton man can boss the midfield battle.

Morocco v Malawi (19:00 GMT)

Malawi and Morocco will also lock horns for the first time in the AFCON at Stade Ahmadou Ahidjo.

Underdogs Malawi will be playing only their 10th game in this competition and they have only won two Africa Cup of Nations matches.

They are unbeaten in two games, though, having remained in the tournament courtesy of a 2-1 win over Zimbabwe and a battling goalless draw against Senegal.

Morocco beat Ghana and Comoros en route to last 16 before a 2-2 draw with Gabon. 

Vahid Halilhodzic's side will under pressure to progress in Yaounde by dispatching a Malawi side that had an average of just 31.5 per cent of possession in the group stage, the lowest of any team.

One to watch: Sofiane Boufal (Morocco)

Boufal is Morocco's leading scorer in the tournament with two and he also created 10 chances 

Only Algeria’s Youcef Belaïli created more opportunities in the group stage with 12 and Morocco will expect the winger to step up again.

Africa Cup of Nations debutants Gambia have continued their impressive run with a shock 1-0 defeat of Guinea that sent the Scorpions into the quarter-finals.

Gambia caused something of an upset just by getting out of their group, as they finished second to Mali, but their campaign shows no sign of stopping after they saw off their West African rivals on Monday.

A tetchy first half had few highlights but both sides did eventually threaten just before the break, as Guinea's Mohamed Bayo was denied at point-blank range by goalkeeper Baboucarr Gaye and Ebrima Darboe shot agonisingly wide at the other end.

The breakthrough arrived 19 minutes from time – Musa Barrow profiting from a fortunate ricochet before bursting into the box and coolly slotting home.

Guinea briefly thought they had levelled soon after, only for Ibrahima Sory Conte II to be flagged offside – he was then caught in the face accidentally as Yusupha Njie was somewhat harshly sent off for a second booking.

The Syli Nationale piled pressure on in the latter stages, hitting the frame of the goal twice in quick succession, but Conte then received his marching orders for a similar offence to Njie and Gambia held out for a famous win that will in all likelihood see them face hosts Cameroon in the last eight.

Youssef Msakni sent a COVID-hit Tunisia into the Africa Cup of Nations quarter-finals with a 1-0 victory over Nigeria, who finished the game with 10 men. 

Tunisia scraped through the group stage and were without head coach Mondher Kebaier and a number of players for the last-16 clash on Sunday after an outbreak of coronavirus in their camp. 

However, they still managed to book a date with Burkina Faso, who overcame Gabon on penalties earlier in the day, in the next round. 

Montassar Talbi had the only shot on target in a dour first half in Garoua, but Msakni's low drive skidded off the turf and into the top-right corner off Maduka Okoye's glove within two minutes of the restart. 

Nigeria were reduced to 10 men in the 66th minute when substitute Alex Iwobi – who had only been on the pitch for seven minutes – had a booking upgraded to a straight red card after referee Maguette Ndiaye reviewed video footage of his tackle on Msakni 

The Super Eagles upped their game as they chased an equaliser, but Moses Simon was unable to beat Bechir Ben Said and Umar Sadiq missed the target in stoppage time as they exited the tournament.

Ismahila Ouedraogo scored the winning spot-kick as Burkina Faso beat 10-man Gabon 7-6 on penalties after a 1-1 draw to advance to the quarter-finals at the Africa Cup of Nations.

A tight game was sent to extra time after a dramatic late equaliser from the Panthers, and an even more tense shoot-out was ultimately decided by the 22-year-old Ouedraogo.

There had been a penalty in normal time after Issa Kabore was brought down by Sidney Obissa in the 14th minute, only for Bertrand Traore to slam his effort against the crossbar.

The Aston Villa man was not to be denied 10 minutes later when he ran on to a through ball from Hassane Bande and slotted in off the post past the onrushing Jean Noel Amonome.

Gabon thought they were level four minutes before half-time as a long ball from skipper Bruno Ecuele Manga found Aaron-Salem Boupendza, who cut inside and finished well but was ruled to be offside.

Obissa received his marching orders in the 67th minute after picking up a second yellow card, but Gabon still forced extra time as a 91st minute corner was headed in by Ecuele Manga, though went down as an Adama Guira own goal after diverting in off the Burkinabe midfielder.

An extra 30 minutes could not separate the sides and so the game went to penalties, with both teams scoring six of their first eight attempts.

After Lloyd Palun hit Gabon's ninth penalty against the bar, Ismahila Ouedraogo finally ended things by sending Amonome the wrong way, booking the Stallions' quarter-final place against either Nigeria or Tunisia next Saturday.

Cameroon were hot favourites to book a quarter-final place even before Comoros revealed they must field an outfield player in goal for Monday's Africa Cup of Nations last-16 clash.

Now hosts Cameroon must keep their focus in the unusual circumstances, while tournament debutants Comoros surely need a footballing miracle.

That is Monday's second knockout game, and it comes after a tussle between Guinea and Gambia in Bafoussam.

Guinea v Gambia (16:00 GMT)

Guinea will be without Liverpool midfielder Naby Keita for this one, after he picked up a second yellow card of the tournament late on in the defeat to Zimbabwe last time out.

The clash at Kouekong Stadium is one between teams that finished second in their respective groups, and Gambia will hope their good fortune holds after arguably riding their luck to reach this point.

Tom Saintfiet's Gambia side have outperformed their expected goals (xG) total, scoring three times from an xG of 2.0, while conceding just once despite an expected goals against (xGA) tally of 4.7. The 3.7 gap between xGA and actual goals conceded was the highest of all teams in the group stage.

Gambia faced the most shots of all teams (58) in the group stage, but remarkably they still kept two clean sheets, including when they pulled off a shock 1-0 win over Tunisia.

Guinea underperformed in their shooting, scoring only twice from an xG of 4.0 across their three group fixtures.

Gambia coach Saintfiet said ahead of the game: "We are not afraid as we have been together with the players for over three years, meaning we have cohesion and great team spirit."

One to watch: Amadou Diawara (Guinea)

Guinea are looking to win their first knock-out match at the Africa Cup of Nations at the sixth attempt, having lost all five of their previous such attempts. Roma midfielder Diawara should be a key figure in their efforts to come through this one, bringing his plentiful Serie A experience to bear.

Cameroon v Comoros (19:00 GMT)

Considering Cameroon were the top scorers in the group stage with seven goals, Comoros would have liked their first-choice goalkeeper fit for this one. Second choice would have been fine, third choice a salvageable situation. But instead they are all out of keepers, with Salim Ben Boina injured and both Moyadh Ousseini and Ali Ahamada testing positive for COVID-19.

The minnows will hope their chosen emergency keeper proves a revelation at Stade d'Olembe, but the prospects for Comoros appear bleak, despite them reaching the knockout stages with a shock 3-2 win over Ghana.

This will be the first Africa Cup of Nations encounter between Cameroon and Comoros, who on Saturday reported a total of 12 COVID cases in their camp.

Cameroon have reached at least the quarter-finals in eight of their last 10 Africa Cup of Nations appearances, although they have failed to do so in two of the previous three editions (group stage in 2015 and last-16 in 2019).

No doubt licking his lips at the prospect of facing Comoros will be Cameroon captain Vincent Aboubakar, top scorer in the tournament with five goals in the group stage. The last players to score more than five goals in a single edition of the Africa Cup of Nations were Egypt's Hossam Hassan and South Africa's Benni McCarthy (both 7) in 1998.

One to watch: The rookie goalkeeper

Whoever gets the gloves faces a daunting challenge. Cameroon attempted 35 shots in the group stage, more than any other side, and also tried 63 crosses (only Senegal and Egypt had more). Comoros shipped five goals in three games when they had a recognised goalkeeper, losing two of their three Group B games. They should be ripe for being picked off by the home team in Yaounde.

Comoros will take on Africa Cup of Nations hosts Cameroon in the last 16 with an outfield player in goal, it has been confirmed. 

After reaching the knockout stages by shocking Ghana 3-2 in their final group game, tournament debutants Comoros announced on Saturday they had returned 12 positive coronavirus tests in their camp. 

Among them were coach Amir Abdou and their only fit goalkeepers Moyadh Ousseini and Ali Ahamada, the latter of whom replaced the injured Salim Ben Boina in the first half against the Black Stars. 

With all three keepers unavailable for Monday's clash with Cameroon, assistant coach Jean-Daniel Padovani confirmed Comoros would have to take on the competition's leading goalscorers with an outfield player between the posts. 

"We've already chosen an outfield player who will start as keeper," said Padovani. "It's a player who in training has shown that he can play as a keeper." 

Comoros only have 12 players available for the game. Competition rules state if a squad is without a goalkeeper but still includes at least 11 fit players, another member of the team must go in goal.

By Sunday evening in Cameroon, the first two quarter-finalists at the Africa Cup of Nations will be known.

Burkina Faso should start as slight favourites against Gabon, chiefly due to their win when the teams met ahead of the tournament.

Nigeria will then be expected to overcome a Tunisia side who qualified for the last-16 stage via the back door.

Burkina Faso v Gabon (16:00 GMT)

Burkina Faso rather scrambled through the group stage, losing their opener to the hosts before winning 1-0 against Cape Verde and drawing 1-1 with Ethiopia.

They were runners-up in 2013 and finished third in 2017, so this is far from uncharted territory and a 3-0 win over Gabon in a warm-up game for this tournament at the start of January may be a guide of what to expect from this tussle in Limbe.

Midfielder Adama Guira is urging caution though, telling the Sidwaya newspaper: "A lot of things have changed on the Gabonese side after this friendly match. Their last outing against Morocco attests to this. They are a very good team."

Gabon were unbeaten in the group stage, despite the disruption of losing captain Pierre-Emerick Aubameyang and midfielder Mario Lemina after brushes with COVID-19. A win over the Comoros was consolidated by draws with Ghana and Morocco.

That pre-tournament loss to the Stallions might be a factor, but Gabon are unbeaten in their previous two AFCON meetings with Sunday's opponents – both having taken place in the group stages (2-0 in 2015 and 1-1 in 2017).

One to watch: Guelor Kanga (Gabon)

Red Star Belgrade attacking midfielder Kanga has been a livewire for Gabon so far in the tournament, with a team-high eight shots and five chances created (one assist). It earned him a place among the substitutes in the tournament's official best team of the group stage.

Nigeria v Tunisia (19:00 GMT)

Nigeria have two players in the group stage's best XI, with centre-back William Troost-Ekong and forward Moses Simon both earning plaudits for their early performances.

Augustine Eguavoen's team were the only side with a 100 per cent winning record in the groups, and now they tackle a Tunisia outfit who only edged through as one of the best third-placed teams, having lost twice already.

These sides are meeting for the sixth time at the Africa Cup of Nations and Tunisia's only successful AFCON meeting with Nigeria came in 2004, when they progressed via penalties in the semi-finals, going on to win the competition.

Nigeria have won 12 of their last 14 AFCON games (L2), and they start this game as hot favourites.

Nigeria have had more different scorers (6) than any other team so far at this year's tournament, with Kelechi Iheanacho, Simon, Simon Chukwueze, Taiwo Awoniyi, Troost-Ekong and Umar Sadiq each scoring once.

One to watch: Kelechi Iheanacho

The Leicester City striker has one goal and one assist so far, creating a team-high six chances. Such evidence points to him being a likely menace to the Tunisian defence.

Mali took top spot in Group F at the Africa Cup of Nations after coasting to a 2-0 win over Mauritania in their final pool fixture.

The Eagles needed simply to better Gambia's result to lead the standings and did so as their rivals won only 1-0 against Tunisia.

Mali were already through regardless, though, and so there was little jeopardy even before Massadio Haidara's second-minute opener – the earliest strike at the tournament so far.

The Lens left-back scored a scruffy first international goal when Moussa Doumbia touched a right-wing cross into his path.

Mauritania never truly looked like responding, although Ibrahima Kone's penalty was ultimately required to pip Gambia, the forward thrashing in after a clumsy foul on Doumbia early in the second half.

A superb 93rd minute strike from Ablie Jallow gave Gambia a dramatic 1-0 win against Tunisia, though both teams had already been guaranteed a place in the last 16 of the Africa Cup of Nations regardless.

Gambia ended the game being leapfrogged for top spot in Group F by Mali on goal difference, who beat Mauritania 2-0, and they will play Guinea in the round of 16, while third placed Tunisia will face Nigeria.

A relatively uneventful game in the main saw plenty of chances but few of note, with Tunisia's Ali Abdi going closest in the early stages as he cut inside from the left and saw his deflected shot fly just wide of the near post.

Ellyes Skhiri fired wide of the far stick with a well-hit effort on 41 minutes but shortly after Tunisia had a penalty when Seifeddine Jaziri was tripped by Pa Modou. Tunisia had missed their first two spot kicks of this tournament, which became three when Jaziri saw his penalty saved well down to his right by Baboucarr Gaye.

When the half-time whistle came, ill-tempered reactions by both teams as they headed off the pitch led to referee Fernando Guerrero Ramirez producing a red card to Tunisia's substitute goalkeeper Farouk Ben Mustapha.

Gambia showed a bit more intent in the second half with Jallow firing wide before Musa Barrow hit the woodwork with a fierce free-kick, but it took until the closing seconds of stoppage time for the deadlock to be broken as Jallow took down a cross from the left and fired the ball hard and high past Bechir Ben Said to win it for the Scorpions.
