RAMALLAH: Prominent Palestinian prisoner Marwan Barghouti’s son has said Israeli guards beat his father during a prison transfer last month, an accusation denied by Israel’s prison authorities.

“Eight guards started beating him up until he passed out,” Arab Barghouti told AFP on Wednesday, describing an incident he said took place on September 14.

Arab Barghouti said he only learnt of the attack after five other inmates who had been with his father were able to communicate with the outside world.

Barghouti, in his 60s, is serving multiple life sentences since 2002 for deadly attacks on Israelis.

A senior leader of Fatah party, he is often described by supporters as the “Palestinian Mandela.”
