Thirty seven Palestinians on Monday have been killed along the Gaza border by Israeli security forces as clashes erupted over the controversial inauguration of the US embassy in Jerusalem.

The death toll made it the deadliest day in the Israeli-Palestinian conflict since the 2014 Gaza war.

The thirty seven, including a 14-year-old, were shot dead by Israeli forces as clashes broke out at five points along the Gaza border hours before the opening of the embassy.

More than 900 Palestinians were wounded in the clashes, the health ministry in Gaza said, with the Palestinian Journalists’ Syndicate saying eight journalists were among them.

The Israeli army said that more than 35,000 people were involved in the protests and clashes.

It accused Gaza’s Islamist rulers Hamas of leading a “terrorist operation under the cover of masses of people”.

The Palestinian Authority government based in Ramallah, in the occupied West Bank, accused Israel of carrying out a “terrible massacre”.

Palestinians threw stones, rolled burning tyres towards the border and tried to approach the fence to damage it and potentially breakthrough, with Israeli snipers firing from the other side.
