Another explosion rocks the Gaza Strip.
The latest blast is part of a five-day offensive by Israel that has battered the enclave and killed more than 51 people - about half of them civilians.
That's according to Palestinian officials.
Now, Prime Minister Benjamin Netanyahu says Israel is prepared to step up the attacks, aimed at the militant group Hamas - which runs Gaza.

"We are exacting a heavy price from Hamas and the terrorist organisations and the Israel Defence Forces are prepared for a significant expansion of the operation."
While air strikes continue, Israel's Cabinet has authorized the mobilization of up to 75,000 reservists in preparation for a possible ground invasion.
Officials say the offensive is in response to attacks by Hamas militants, who have fired more than 500 rockets into Israel, killing three people.
