It came after he accused Israel of "knowing very well how to kill" during a heated debate at the World Economic Forum.

Erdogan stormed out of a debate on Israel's Gaza offensive on Thursday, and vowed he might never return to the annual gathering of the rich and powerful in Davos.

President Shimon Peres had launched a fiery defense of his country's offensive in Gaza over the past month, and with a raised voice and pointed finger, questioned what Erdogan would do if rockets were fired at Istanbul every night.

"When it comes to killing, you know very well how to kill," Erdogan, visibly angry, responded as he sat next to Peres at the debate, which also included United Nations Secretary General Ban Ki-Moon and Arab League chief Amr Moussa.

Turkey, a predominantly Muslim but secular country that historically has had good ties with Israel and the Arab world, played a role in helping broker an end to the Gaza offensive this month, particularly by lobbying the Islamist Hamas group to declare a ceasefire.

Thousands of people gathered at Istanbul's Ataturk airport to greet Erdogan when he returned, waving Turkish and Palestinian flags and chanting "Turkey is proud of you."

"Our people would have expected the same reaction from any Turkish prime minister," he told a news conference at Ataturk airport on Friday morning after speaking to the crowd.

"This was a matter of the esteem and prestige of my country. Hence, my reaction had to be clear. I could not have allowed anyone to poison the prestige and in particular the honor of my country," he said.

"Our reproaches are not against the Israeli people or Jews. Our reproach is totally against the Israeli administration," Erdogan said.

Turks gave a mixed reaction to Erdogan's walk-out, former diplomats saying it was likely to fuel tension between Israel and Turkey and might weaken Ankara's position as a neutral mediator in the Middle East.

"The spirit of Davos died," said a headline in the top-selling Hurriyet newspaper. "A historic slap," the Yeni Safak daily, which has close links to the ruling AK Party, said of Erdogan's strong criticism of Israel.

Broadcaster CNN Turk said Hamas had praising Erdogan.

100 rockets

Peres had asked Erdogan directly at Davos: "What would you do if you were to have in Istanbul every night a hundred rockets?"

Erdogan had responded strongly to Peres's repeated question to the panel of what they would do in Israel's position.

"President Peres you are older than me and your voice is very loud. The reason for you raising your voice is the psychology of guilt. I will not raise my voice that much, you should know that. When it comes to killing you know very well how to kill. I know very well how you hit and killed children on the beaches," he said during the panel discussion.

Peres said on Friday he hoped relations with Turkey would not be affected by the heated exchange.

"We don't want conflict with Turkey. We are in a conflict with the Palestinians," Peres told reporters in Davos.

Turkey has harshly criticized Israel over its Gaza offensive, in which Israeli forces killed more than 1,300 Palestinians. Israel lost 10 soldiers and 3 civilians.

Erdogan's rhetoric has shocked Israel, and has been interpreted by some as an attempt to increase his support ahead of local elections in March with an electorate deeply sympathetic to the Palestinians.

"Prime Minister Erdogan's tantrum at Davos throws gasoline on the fire of surging anti-Semitism," American Jewish Committee Executive Director David Harris said in a statement.
