An Israeli basketball team fled to the changing room in Ankara on Tuesday as hundreds of fist-pumping, chanting Turkish fans protested the violence in Gaza.
The European Cup game between Bnei Hasharon and Turk Telekom was later postponed because the Israeli team did not return to the court.
There was no word on when or where the game would be played.
The fans chanted "God is Great" and "Killer Israel." At least one fan threw his shoe at Israeli players, but police used riot shields to protect them as they left the court. The Turkish players also headed to the locker-room.
A pro-Islamic group earlier set an Israeli flag on fire outside the arena.
In addition to several Israelis, Hasharon's roster includes a number of Americans, a Nigerian, and former NBA draft pick Ousmane Cissi, who was born in Mali.
Turkey has harshly criticized Israel over the ground offensive in Gaza and has urged an immediate ceasefire in the Palestinian territory. It has also called on the United Nations to take steps to end the violence.
Israel says it acted to stop rocket attacks from Islamic Hamas militants.
