Turkey says US shares responsibility for Gaza 'massacre'

The United States shares responsibility with Israel for today's "massacre" along the Gaza border in which 37 Palestinians were killed, Turkey's deputy prime minister said.

"The US administration is as responsible as the Israeli government for this massacre," Bekir Bozdag wrote on Twitter, saying the violence was sparked by "unjust and unlawful decisions" in reference to Washington moving its embassy from Tel Aviv to Jerusalem.

Violent clashes erupted along Gaza's border hours ahead of the opening of the US embassy in Jerusalem, which was to be attended by a White House delegation and Israeli officials.

Turkish President Recep Tayyip Erdogan and other officials have repeatedly condemned the US decision to move the embassy, warning it risked inflaming tensions.

"The US administration moving its embassy to Jerusalem destroyed the chances for peace and ignited a fire that will cause more human losses and injuries as well as destruction and catastrophe in the region," said Bozdag, who is also government spokesman.

"From now, nothing will be the same in the causes of Palestine and Jerusalem," he added.
