Gaza poised for further violent protests
Fresh protests against Israel are expected in the Palestinian territories, a day after Israeli troops killed 55 people in Gaza.
Tuesday marks the 70th anniversary of what Palestinians call the Nakba, or Catastrophe, that saw thousands flee amid the creation of Israel in 1948.
Tensions will be particularly high in Gaza where funerals for those killed on Monday are due to take place.
The violence came as the US opened a controversial embassy in Jerusalem, BBC reports.
The move of the US embassy from Tel Aviv has incensed Palestinians, who claim eastern Jerusalem as the capital of a future Palestinian state.
They see the US move as backing Israeli control over the whole of the city, which Israel regards as its indivisible capital.
Palestinian officials said that, as well as those killed, about 2,700 people were injured in Monday's violence. It was the deadliest day in Gaza since the 2014 war.
Israeli PM Benjamin Netanyahu said his military was acting in self-defence against Gaza's Islamist rulers, Hamas, who he said wanted to destroy Israel.
The Palestinian Authority's leader condemned a "massacre". The UN spoke of "outrageous human rights violations".
