Relations between Israel and the main United Nations agency helping Palestinians are plumbing new depths, with the Sharon Government accusing the UN of harbouring terrorists within the ranks of the body known as the UN Relief and Works Agency for Palestinian Refugees, UNRWA.
Israel says that two UNRWA workers were members of the militant group, Hamas.
The man and woman concerned are now dead after an Israeli Army raid. That takes to four the number of UNRWA staff killed in the past three weeks. The first to die was a British UNRWA worker, shot by an Israeli soldier.
To compound the crisis in the relationship, Israel's Army has demolished a building containing hundreds of tonnes of UN food aid.
