Gaza has come under renewed bombardment from Israel, as agreement on a ceasefire to end a week of violence remains elusive.
At least 20 Palestinians were reported to have been killed yesterday.
Two Israelis - a soldier and a civilian - were killed in rocket strikes.
Earlier, Egyptian and Palestinian officials said a ceasefire would shortly be announced at talks in Cairo.
Gaza militants said they were awaiting Israeli approval of a Cairo-brokered truce to their seven-day conflict as US Secretary of State Hillary Clinton arrived in the region to make an urgent push for peace.
