Ahmet Davutoglu said in an interview aired on Ulke TV late Thursday that he believes Israel “has gained sufficient experience” after last year’s Israeli raid on a flotilla that killed eight Turks and one Turkish-American and sparked international outrage. Each side accused the other of starting the violence.

A coalition of pro-Palestinian groups say a flotilla will set sail in the third week of June. Israel has vowed to stop any attempt to breach its sea blockade of Gaza.

A Turkish Islamic aid group said it expects the convoy to be at least twice as big as the one that attempted to reach Gaza last year.
