Turkey's prime minister Tayyip Erdogan left the World Economic Forum saying he might never return to the annual gathering . Israel's president Shimon Peres had launched a fiery defence of his country's assault on 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. Turkey's state-run Anatolian news agency quoted Erdogan as saying to Peres: "When it comes to killing you know very well how to kill. I know very well how you killed children on the beaches." In a news conference, Erdogan later explained that he had been upset with both the moderation of the debate and Peres manner. Later he went out from the room and when he reached his country he called as " NATIONAL HERO" Really its very nice to see this heroism for all. Thanks DRIROTA 31-01-09
