CAIRO, June 23 (Reuters) - Eight Palestinians were killed on Sunday in an Israeli airstrike on a training college near Gaza City being used to distribute aid, Palestinian witnesses said, as Israeli tanks pushed further into the southern city of Rafah.

The strike hit part of a vocational college run by the U.N. Palestinian refugee agency UNRWA now providing aid to displaced families, the witnesses said.

“Some people were coming to receive coupons and others had been displaced from their houses and they were sheltering here. Some were filling up water, others were receiving coupons, and suddenly we heard something falling. We ran away, those who were carrying water let it spill,” said Mohammed Tafesh, one of the witnesses.

A Reuters photographer saw a low-rise building completely demolished and bodies wrapped in blankets laid out beside the road, waiting to be taken away.

Juliette Touma, UNRWA’s Director of Communications, said the agency was looking into the details of the reported attack before providing more information. “Since the beginning of the war, we have recorded that nearly 190 of our buildings have been hit. This is the vast majority of our buildings in Gaza,” she said. A total of 193 UNRWA team members had been killed in the conflict, she said.
