On Wednesday the U.N. said Hamas police seized thousands of blankets and food packages destined for Gazas needy residents.
This move could possibly threaten the U.N.'s provision of aid to the impoverished Gaza strip.
A United Nations Relief and Works Agency spokesperson, Christopher Gunness, said Hamas policemen broke into an aid warehouse in Gaza City on Tuesday evening and confiscated 3,500 blankets and more than 400 packages of food, the Associated Press reported.
Gunness said, They were armed, they seized this, they took it by force, and has termed the seizure as absolutely unacceptable.
He said police confiscated aid meant for 500 families after U.N. officials refused to voluntarily hand it over to the Hamas-run Ministry of Social Affairs. Similar U.N. aid packages had already been distributed to 70,000 residents over the past two weeks.
More than half of Gaza's 1.4 million residents rely on U.N. food, education and health care. However tensions between the UNRWA and Hamas could harm international donations.
The European Commission, which contributed $626 million to the Palestinians in 2008, indicated that a repeat seizure could affect donations.
A donor's conference is scheduled to be held in Cairo later this month.
