The family of the most prominent Palestinian prisoner, Marwan Barghouti, says that he has again been subjected to physical violence behind bars in Israel. Arab Barghouti told the BBC he was shocked and appalled to hear from his father's Israeli lawyer that he had been assaulted three times by Israeli prison guards in the past month.

The Israeli Prison Service (IPS) said that the allegations made are false and baseless.

Marwan Barghouti was convicted by an Israeli court of planning deadly attacks against Israeli civilians and is currently serving five life sentences plus 40 years. He was arrested exactly 24 years ago, at the height of the Palestinians' second intifada. He had set up the Tanzim, an armed wing of the Fatah political faction.

Opinion polls indicate that despite his imprisonment, Barghouti is the most popular Palestinian leader. He remains a member of the Fatah Central Committee. Many Palestinians view the 66-year-old as their equivalent of South Africa's Nelson Mandela and point to his ability to unite different political factions and his rapport with Israeli leaders.

His son, Arab Barghouti, argued that his father's prominence had led to him being singled out for attacks and abuse. He's someone who represents hope for unity, for democratic renewal, for a better future for the Palestinian people, he said. He's a target because he gives hope to the Palestinian people.

The Israeli lawyer, Ben Marmarelli, visited Marwan Barghouti in prison on Sunday. He wrote on X that three weeks earlier, guards entered his client's cell in Megiddo Prison and repeatedly attacked him with a guard dog, and he was then beaten during his transfer to another Israeli jail. One week ago, in Ganot Prison, Marmarelli said that Barghouti was severely beaten and left bleeding for more than two hours. He requested medical care and was denied treatment.

Since the deadly Hamas-led attacks on Israel on 7 October 2023, UN agencies and Israeli rights groups have reported an increase in claims of abuse of Palestinian prisoners, including routine beatings and severe medical negligence. Human rights groups attribute this to an established Israeli policy. The IPS denies claims of systematic abuse and states that incidents of misconduct are investigated.

Marwan Barghouti is understood to have been kept in solitary confinement for the past two-and-a-half years. His family claims he has previously been severely beaten by Israeli guards and that on one occasion he suffered four broken ribs and head injuries. Arab Barghouti expressed outrage that Western leaders have not spoken out against the treatment of prisoners, suggesting this leads to the dehumanisation of Palestinians.
