The UN humanitarian office has said that there have been some “issues” getting aid into Gaza through the Rafah crossing with Egypt, which it said had been designed for pedestrians, not trucks.

Only 65 trucks carrying food, medicine, hygiene supplies and water, and seven ambulances, crossed from Egypt into Gaza on Wednesday, it said.

“We cannot drive to the north at the current point which is of course deeply frustrating because we know there are several hundred thousand people who remain in the north,” said OCHA spokesperson Jens Laerke.

“If there is a hell on earth today, it’s name is northern Gaza,” he said. “It is a life of fear by day and darkness at night and what do you tell your children in such a situation, it’s almost unimaginable — that the fire they see in the sky is out to kill them?” he said.
