The United Nations Relief and Works Agency (UNRWA) condemned Thursday the attack against its Summer Games facility in north-west Gaza. According to a statement issued by the UNRWA, ten men attacked and vandalised the Summer Games facility in north-west Gaza where later today UNRWA will attempt a world record for the largest number of children flying kites. UNRWA Spokesman Chris Gunness said the attackers damaged a large billboard, burnt a UN flag and torched part of the stage. None of the UN security personnel at the venue were harmed. \"We condemn this attack, which is an attack on the children of Gaza as much as on the United Nations,\" Gunness, adding \"we call on the authorities in Gaza to investigate and bring those responsible to account.\"
