Israel defends actions as 55 Palestinians killed

In the deadliest day of violence in Gaza since the 2014 war, Palestinian officials say Israeli troops have killed 55 people and wounded 2,700.

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".

The violence came as the US opened a controversial embassy in Jerusalem.

The move of the US embassy from Tel Aviv has incensed Palestinians, who claim eastern Jerusalem as the capital of a future Palestinian state.
