Turkish fans booed during the minute’s silence for the victims of the Paris attacks before their national team drew 0-0 with Greece in a friendly international soccer game on Tuesday, Reuters reports.

According to The Daily Mail, chants of ‘Allahu Akbar’ were reportedly heard in Istanbul as some Turkey fans shamefully booed a pre-match minute’s silence for the victims of the Paris attacks.

The mark of respect was observed at matches across Europe, including at Wembley where France faced England, after Islamic State militants struck Paris on Friday killing 129 people.

Turkish Prime Minister Ahmet Davutoglu and Greek counterpart Alexis Tsipras watched the game together, in a sign of reconciliation between the two neighbors, whose relationship has suffered from hostilities in the past.

It was the first time the two teams had met for eight years and the Turkish Football Federation had announced a string of additional security measures before the match at the Istanbul Basaksehir stadium, which was a 17,000 sell out.
