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.
But a spokesman for the Israeli Defense Forces, Lt Col Peter Lerner, said the Israeli military did not knowingly target UN buildings.
And he said it was ''a huge challenge... to keep civilian impact to a minimum''.
