Hamas, which controls Gaza, is still discussing the plan, but its armed wing has rejected it as a "surrender".

Under the terms, the ceasefire should begin immediately, followed by a series of meetings in Cairo with high-level delegations from both sides.

Palestinian officials say at least 192 people have been killed by Israeli air strikes launched eight days ago to stop militants firing rockets into Israel.

There have been no Israeli air strikes into Gaza since the 09:00 ( 06:00 GMT) truce, but Israel says 39 rockets have been fired from Gaza into Israel after the deadline.

US Secretary of State John Kerry said he could not "condemn strongly enough" Hamas' actions in continuing to fire rockets despite the ceasefire call.
