Turkish President Tayyip Erdogan called Israel a "terror state" on Saturday after Israeli police fired rubber bullets and stun grenades towards rock-hurling Palestinian youth at Jerusalem's Al-Aqsa mosque on Friday.
He added that Ankara had launched initiatives to mobilize international institutions.
The clashes at Islam's third-holiest site and around East Jerusalem, which injured at least 205 Palestinians and 17 police officers, came amid mounting anger over the potential eviction of Palestinians from homes on land claimed by Jewish settlers. Israel's Supreme Court will hold a hearing on the case on Monday.
Speaking at an event in Istanbul, Erdogan called on all Muslim countries and the international community to take "effective" steps against Israel, adding that those who remain silent were "a party to the cruelty there."
