GAZA CITY (Ma'an) -- A summer camp facility in north-west Gaza run by the Palestinian refugee agency was vandalized by unknown assailants at dawn Thursday, UNRWA said in a statement.
Ten men entered the camp shortly after midnight, when they burnt a UN flag, damaged a large billboard, and torched part of the camp stage. None of the UN security personnel at the venue were harmed, UNRWA said.
In a statement condemning the attack, UNRWA Spokesman Chris Gunness said the agency would repair the damage and go ahead with a world record breaking attempt for the largest number of children flying kites, planned for 6 p.m. the same day.
The arson "is an attack on the children of Gaza as much as on the United Nations," Gunness said.
"We call on the authorities in Gaza to investigate and bring those responsible to account."
At dawn on Wednesday, a group of 30 armed and masked men burned the Rais resort in Gaza and threatened employees.
In the summer of 2010, two UNRWA summer camps were torched on separate occasions.
Camp organizers say the UNRWA Summer Games is the largest recreational program in Gaza, putting on games and contests for an estimated quarter of a million children.
