US Secretary of State John Kerry, in Istanbul for talks on Syria, has urged Turkey and Israel to work towards improving relations.
The relationship hit an all time low in 2010 when Israel attacked a Gaza-bound aid flotilla that left eight Turks dead and one Turkish American.
Israeli and Turkish diplomats are due to meet later this week to discuss Israeli compensation for the victims of the flotilla attack.
Israel recently apologised for the incident:
John Kerry was pains to highlight a rare Israeli apology: “That was a courageous decision made by the prime minister of Israel, to move forward in that relationship, and I believe that Prime Minister Erdogan and Foreign Minister Davutoglu are deeply committed to fulfilling all the obligations of that understanding,” he said.
Kerry also implored Erdogan not to undertake a planned trip to the Hamas-controlled Gaza Strip a move backed by Palestinian President Mahmoud Abbas.
Kerry believes the window of opportunity for a two-state solution of the Israel-Palestinian conflict is closing quickly and he wants to move fast to find some kind of resolution.
