Turkey's government on Tuesday expelled the Israeli ambassador in protest over Israel's killing of dozens of Palestinian protesters in Gaza, a Turkish foreign ministry official said.
The Turkish decision marked one of the strongest international responses after Monday's deadly confrontations along the border fence separating Israel and Gaza, which has been under Israeli blockade for more than a decade. At least 60 people were killed and more than 2,000 injured, Gaza officials said.
Turkey maintains diplomatic ties with Israel, but relations have been severely strained in recent years over issues including the treatment of Palestinians.
In 2010, Israeli commandos stormed a Turkish-operated passenger vessel, the Mavi Marmara, that was on a course to breach Israel's naval blockade of Gaza. The raid killed nine activists.
On Monday, thousands of Turks attended a protest in Istanbul. Meanwhile, Turkish officials announced that Turkey's ambassadors to Tel Aviv and Washington were being recalled for consultations in protest at the Gaza killings.
Turkish President Recep Tayyip Erdogan, speaking during a trip to Britain, called the Gaza killings "a genocide."
"They are not committing this genocide for the first time," he said, adding that the killings "have shown the ugly face of Israel."
Reacting on Twitter, Israel's prime minister, Benjamin Netanyahu, said: "Erdogan is among Hamas's biggest supporters and there is no doubt that he well understands terrorism and slaughter. I suggest he not preach morality to us."
