The Gaza Strip's Hamas premier Ismail Haniyeh is in Turkey for meetings with Turkish Prime Minister Recep Tayyip Erdogan and the head of an Islamic aid group whose Gaza-bound vessel was the target of a deadly raid by Israeli troops in 2010. Haniyeh is on an official tour of the Muslim world, his first trip outside the blockaded territory since the Islamist group took over Gaza in 2007. Turkey's ties with Israel, a former ally, deteriorated sharply over the flotilla raid that killed nine activists on the Turkish boat in 2010, and Erdogan has demanded that Israel lift all restrictions on the Palestinian territory. Haniyeh is scheduled to meet Erdogan at his Istanbul residence on Sunday afternoon. On Monday, he will meet officials of the Islamic aid group IHH.
