Ban Ki-moon said on Thursday that he was angered by the "unacceptable" Israeli attacks on UN compounds that left 44 civilians dead and several others injured.

"Over the past several weeks, unacceptable and terrible situations have taken place against the civilian people and against particularly the United Nations compounds, where many civilians were sheltered," he said at the World Economic Forum in Davos.

UN officials say they have evidence that white phosphorous was used in an attack on the UN's main building in Gaza.
