Arab Barghouti, son of imprisoned Palestinian leader Marwan Barghouti, has called on international human rights organisations to take stronger action against Israel's treatment of Palestinian detainees. The appeal comes as Marwan Barghouti's lawyer reports escalating attacks against the veteran political figure in Israeli custody, including an incident in which he was allegedly left bleeding for hours without medical attention. Arab Barghouti argues that existing advocacy has fallen short and that greater pressure is needed to protect prisoners facing what he describes as systematic abuse.
