Anti-Israeli protests have broken out in numerous countries in the Arab world.
Observers say the raid on the aid flotilla in international waters looks certain to damage Israel’s international standing.
One protester in Istanbul said: “Palestine concerns all of us. We might be Muslim but just being human is enough for us to try to defend Gaza and to condemn this attack. It’s not possible to accept what Israel has done today.”
Protesters tried to storm the Israeli consulate in Istanbul, but were broken up by police. Security has now been stepped up at all of Israel’s overseas embassies.
Jordan is another country that has condemned the raid, calling it a “horrible” crime. Israel’s ambassador to Amman has been summoned for talks at the Jordanian foreign ministry.
In Lebanon, the government says Prime Minister Saad Hariri has called for an emergency meeting of the UN Security Council to discuss the deadly raid. The council is currently chaired by Lebanon.
