Recently, the UN's World Food Programme and Unrwa, the agency for Palestinian refugees, said they had used up all their stocks of food aid.

It found the killing of the Unrwa employee meanwhile "involved a breach of orders during a combat setting".

Last year Israel severed ties with Unrwa, accusing it of colluding with Hamas.

He described Unrwa as a "shining example of multilateralism at the UN" and called for a place where Palestinian families could be "reunited in life rather than death".

At issue are two bills passed by Israel's parliament in October that declared Unrwa harboured terrorists, and ordered the government to end all co-operation and contact with the organisation, including the supply of visas to Unrwa international employees.
