Gaza and Israel hit as truce talks continue in Egypt
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 on Tuesday. 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.
