Dozens of Palestinians, angry over Israel's bloodiest raid in the Gaza Strip in years, smashed the windows of a UN car on Saturday and mobbed a shipment of humanitarian aid.
Cars in the UN convoy were attacked as it entered a sealed-off neighbourhood in Rafah refugee camp to survey damage and deliver aid supplies, including powdered milk.
Israel pulled many troops and tanks out of the camp on Friday following international pressure to end more than three days of fighting but denied the operation, in which 42 Palestinians were killed and hundreds left homeless, was over.
In the Tel al-Sultan neighbourhood, witnesses said the army pulled out its armoured vehicles but continued to cut off access roads to the rest of the camp, and had left residents without
power or running water for days.
An Israeli army spokeswoman said international relief workers in the past few days were allowed to deliver aid, such as medicine, food and water, to residents in the camp. The United Nations confirmed one shipment had reached the camp.
Inside Tel al-Sultan, roads were ripped up by tank tracks, which also ruined outlying fields. Armoured vehicles and tanks blocked the entrance to the neighbourhood, preventing residents from entering or leaving.
Dozens of Palestinian men and boys gathered at the entrance to Tel al-Sultan and a few threw stones at cars in the convoy, which carried UNRWA chief Mr Peter Hansen.
Mr Hansen said bodies of Palestinians who died in the raid, many of them from Tel al-Sultan, were in a morgue because their families were unable to come out and bury them.
The Israeli army, which said it was searching for tunnels used for arms smuggling dug under the Egypt-Gaza border, mounted its biggest Gaza raid in years after militants killed 13 soldiers last week.
