Hamas has accepted the latest proposal for a 60-day ceasefire with Israel that includes the return of half the hostages the group holds in Gaza and Israel's release of some Palestinian prisoners, an Egyptian official source said on Monday.

The official said it is almost identical to an earlier proposal accepted by Israel, which has not yet joined the latest talks.
