Most outspoken though has been Prime Minister Recep Tayyip Erdogan himself.
He has referred to Israeli action in Gaza as "savagery", "a crime-against humanity" and "state terror," and warned Israel that it will "reap what it sows". "People say my statements are too harsh," Mr Erdogan said on Tuesday. "They are no harsher than the phosphorus bombs used by Israel.
"Civilians and children are dying in Gaza," he added. "Those who keep their silence over these attacks out of whatever concern or for whatever diplomatic reason, will pay the price before history."
