Dozens of Palestinians attacked a United Nations compound in Gaza City following the world body's suspension of an aid program for victims of last year's war.

The Palestinians involved in the Wednesday incident were protesting the decision to halt aid because of a shortfall of funding from donor countries.

The protesters jumped over the compound's walls and smashed guard cabins and windows. They burned tires and threw stones at the compound's gate.

The U.N. said it was "outraged by the assault." It said the Islamic militant group Hamas, which rules Gaza, knew of the planned protest but did not take appropriate measures to protect the compound.

The U.N. Palestinian refugee agency said it needs $720 million to help 96,000 families whose homes were damaged or demolished in the 2014 war.
