Gaza has come under renewed bombardment from Israel, as agreement on a ceasefire to end a week of violence remains elusive.

A number of explosions overnight left parts of the territory without power.

Earlier, US Secretary of State Hillary Clinton arrived in Israel to support peace moves being brokered in Cairo.

At least 20 Palestinians were reported to have been killed on Tuesday. Two Israelis - a soldier and a civilian - were killed in rocket strikes.

Egyptian and Palestinian officials had said on Tuesday that a ceasefire would shortly be announced at talks in Cairo.

But Israeli spokesman Mark Regev told the BBC a deal was not yet done.

"I have no doubt that Hamas would be more than happy to have a temporary respite - a time out... so they could rest and re-arm and we would have missiles on Israel next week or next month. We are not interested in that," he said.

A senior Hamas official, Izzat Risheq, said a deal might not be reached until later on Wednesday.
