Israel launched a deadly attack on a UN school housing refugees in Gaza despite repeated warnings that civilians were sheltering there, the UN has said.

UN spokesman Chris Gunness said "the world stands disgraced" by the attack, in which 15 were reported killed.

The Israeli military said an initial inquiry suggested soldiers responded after militants had fired mortar shells "from the vicinity of the [UN] school".
