Presidential spokesman Ihab Fahmy said that the President's decision was based on his "respect for freedom of expression."
1500 GMT: Turkey and Israel. Turkish Minister of Energy Taner Yildiz has said that it is too early to talk of energy deals with Israel despite signs of reconciliation between the two countries; however, he said Turkey was open to energy cooperation in the future.
Last month, Israeli Prime Minister Benjamin Netanyahu apologised to Turkish counterpart Recep Tayyip Erdogan for the slaying of nine Turkish civilians aboard a Gaza-bound ship by Israeli commandoes in May 2010.
"The reason for Israel's apology was not energy projects. But the consequence could be energy projects," Yildiz told reporters at an energy conference in Ankara.
"We have said we are not closed to these in the future. But at this stage ... it is early to talk about energy projects."
