Turkish fans booed during a moment of silence held Tuesday for the 129 victims of the Paris terror attacks before the start of a friendly international soccer match in Istanbul. Players took part in the moment of silence on field before kickoff Tuesday between Turkey and Greece, but several fans in the stands could be heard jeering and booing during the minute. Chants of "Allahu Akbar," or "God is greater," then broke out among fans, a Reuters reporter at the scene said.

The attacks in Paris included three explosions near Stade de France, France’s national stadium, where a friendly soccer match against Germany was in progress and French President François Hollande was in attendance. Ahead of Tuesday's match, the Turkish Football Federation announced there would be additional security measures at Istanbul Basaksehir stadium, where as many as 17,000 people were in attendance. Tuesday's booing wasn't the first time Turkish fans have jeered during a moment of silence. In October, crowds booed during a moment held for Ankara terror victims, the Washington Post reported.
