UEFA has hit Fenerbahce with a partial stadium closure after fans chanted the name of Russian president Vladimir Putin during a Champions League qualifier against Ukraine's Dynamo Kyiv.

Russia invaded Ukraine in February and the war has caused thousands of deaths while millions have been displaced.

The chanting started after Oleksandr Karavayev scored what ended up being the winner for the Ukrainian side in the tie's second leg in Istanbul as they ran out 2-1 victors on aggregate.

It led to Dynamo boss Mircea Lucescu boycotting the post-match news conference, and UEFA has now sanctioned the Turkish club for the behaviour of their fans.

The club have been fined €50,000, while a partial closure of at least 5,000 seats has been ordered for Fenerbahce's next European home game for "the throwing of objects and transmitting a provocative message of an offensive nature, i.e. illicit chants."

UEFA has opened an investigation into the Champions League qualifying second leg between Fenerbahce and Dynamo Kyiv, during which fans of the Turkish club seemed to chant the name of Russian president Vladimir Putin.

Russia's invasion of Ukraine began in February and has resulted in thousands of deaths and the displacement of millions.

Dynamo boss Mircea Lucescu boycotted the post-match news conference in protest, with the chants arriving after Oleksandr Karavayev scoring what turned out to be the winner for the Ukrainian side in the second leg in Istanbul, which finished 2-1 on the night and on aggregate.

According to Ukrainian news outlet Expres, Lucescu told broadcasters: "We cannot accept the behaviour of the fans. I did not expect such chants. It is a pity."

UEFA released a statement on Thursday confirming the incident will be investigated, saying information on the matter will be available "in due course."

"In accordance with Article 31(4) of the UEFA Disciplinary Regulations, a UEFA Ethics and Disciplinary Inspector will conduct a disciplinary investigation regarding alleged misbehaviour of Fenerbahce supporters during the 2022/23 UEFA Champions League second qualifying round, second leg match between Fenerbahce SK and FC Dynamo Kyiv played on 27 July 2022 in Istanbul, Turkey," the statement read.

Dynamo Kyiv boss Mircea Lucescu expressed outrage after fans of opponents Fenerbahce sang the name of Vladimir Putin in Wednesday's Champions League qualifier.

Lucescu boycotted the post-match news conference in protest, with the chants beginning after Oleksandr Karavayev gave the Ukrainian visitors a decisive 2-1 lead in the second leg in Istanbul.

The goal came in the 114th minute, after the teams were level at 1-1 at the end of normal time, and it proved to be a match-winner. It was enough to give Dynamo a 2-1 aggregate victory, carrying them through to the third qualifying round, where they will face Sturm Graz of Austria.

According to Ukrainian news outlet Expres, Lucescu told broadcasters: "We cannot accept the behaviour of the fans. I did not expect such chants. It is a pity."

Russia's ongoing invasion of Ukraine, ordered by president Putin, has led to the deaths of thousands of civilians and forces defending the country, while millions of refugees have fled to neighbouring nations.

The United Nations on July 18 said it had recorded 5,110 civilian deaths since Russia's attack began on February 24, plus a further 6,752 injured.
