Turkey has called for an emergency meeting of the Organisation of Islamic Cooperation (OIC), the Turkish government spokesman Bekir Bozdag said.
The meeting of the 57-member-state body will be held on May 18.
Israeli troops shot dead 55 Palestinian protesters on the Gaza border yesterday as the United States opened its embassy to Israel in Jerusalem.
Turkish President Recep Tayyip Erdogan described the actions of the Israeli forces as a “genocide” and Israel as a “terrorist state”.
The country's Prime Minister Binali Yildirim said the United States was an accomplice in a crime against humanity.
"Unfortunately, the U.S. has arrogantly stood by the Israeli administration which kills civilians and has partnered in this crime against humanity," Reuters cited Yildirim as saying.
"This provocation will only worsen the problems in the region and cause a deeper mark in the Israeli-Palestinian relationship, and will make peace in the region more difficult," he added.
He said U.S. President Donald Trump was attempting to distract attention from domestic problems by moving the embassy, "trying to hide the fire inside by setting fires outside."
