U.S. and Arab mediators are working round-the-clock to hammer out a ceasefire deal between Israel and Hamas, sources close to the talks said, while in the Gaza Strip medics said Israeli strikes had killed 13 Palestinians on Thursday.

Efforts to strike a Gaza truce and hostage release deal between Israel and Hamas have repeatedly failed over key stumbling blocks, but recent negotiations have raised hope of an agreement.Hamas officials told AFP that the current framework for a deal would see the implementation of a ceasefire and the gradual release of hostages over three phases.

The order included four residential block areas in a refugee camp where Israel claims Palestinian militants fired rockets from.
