ANKARA, May 14 (Xinhua) -- The Turkish Prime Minister Binali Yildirim on Monday slammed the Israeli violence against Palestinian protesters after the relocation of U.S. embassy as "a cowardly massacre."

Speaking at Esenboga Airport in the capital Ankara,Yildirim condemned Washington's decision to move its embassy from Tel Aviv to Jerusalem, and declared it "null and void."

He vowed to stand together with Palestine people until they gain the freedom and legitimate rights.

"Palestine is not alone. Jerusalem is not alone. Occupation will end and truth and justice will prevail," Ibrahim Kalin, Turkey's presidential spokesman, wrote on his Twitter account on the same day.

Turkish Justice Minister Abdulhamit Gul also criticized on his Tweeter: "We cannot accept the unlawful attacks against Jerusalem's status and Palestinians' fundamental rights. Palestine and Jerusalem are not alone."

At least 55 Palestinians were killed and over 2,700 others wounded in clashes with Israeli security troops Monday on the border between Israel and Gaza, amid mass demonstrations to protest over the U.S. move of its embassy to Jerusalem.
