Gaza UN shelter attack 'totally unacceptable' - White House

The US has said the shelling of a UN shelter in Gaza is "totally unacceptable and totally indefensible".

In its strongest criticism yet of Israel's offensive in the Palestinian territory, the US - Israel's closest ally - urged Israel to do more to protect civilian life.

A quarter of Gaza's population has been displaced by the fighting, the UN says.

Israel says its operation in Gaza is designed to defend its population from attacks by Palestinian militants.

It blames the Hamas militant group for most of the civilian deaths in Gaza, saying its fighters deliberately operate from civilian areas.
