Prisoner was tortured before dying in Israeli jail, says Palestinian Authority Palestinian students take cover from tear gas fired by Israeli security forces during clashes in the village of Saair following the death of a Palestinian prisoner held in Israel. Photograph: Hazem Bader/AFP/Getty Images A Palestinian prisoner whose death in Israeli custody fanned violent clashes across the West Bank over the weekend was tortured before he died, the Palestinian Authority has said. The results of an autopsy conducted in Tel Aviv were revealed at a press conference in Ramallah on Sunday evening after a day of angry protests across West Bank and Gaza in which dozens were injured. The findings contradict claims by the Israeli prison service that Arafat Jaradat died on Saturday from a cardiac arrest. A Palestinian doctor's investigations found that while Jaradat's arteries were clear, his bruised and bloody body suggested he had been beaten in the days before his death. The 30-year-old, a petrol station worker and father of two, was arrested on 18 February in relation to a stone-throwing incident in November during which an Israeli was slightly injured. Aside from an old back injury inflicted by a teargas canister, his relatives insist he was healthy when he was arrested. Just a few days later, he died in Megiddo prison.. Kameel Sabbagh, a lawyer who attended Jaradat's last hearing on Thursday, has claimed that he had advised the Israeli Judge that his client had been tortured and should be examined by the prison doctor. According to Sabbagh, this did not happen. "He had serious pains in his back and other parts of his body because he was being beaten up and hanged for many long hours while he was being investigated," Sabbagh told Ma'an news agency. Sabbagh's notes from the court hearing describe his client as "extremely afraid" of returning to his cell. A rumour that he had been beaten to death during an interrogation spread quickly through Hebron on Sunday where hundreds of protesters clashed with Israeli soldiers for the second day running in the streets kilometres from Jaradat's home. "When the soldiers came to arrest him last week, they told him say goodbye to your wife and your babies, you won't be seeing them again," said Mohamed Hashlamon, 58, as he watched masked Palestinian youths hurl concrete blocks from the roof above his home in downtown Hebron to arm themselves with the rubble. A phalanx of Israeli soldiers lining the border between the Israeli and Palestinian quarters answered rocks with rubber bullets and tear gas. Three Palestinians and one Israeli soldier were injured in the clashes. People here are angry. They will fight until night fall and they will protest again from 10am tomorrow just as they did yesterday," Hashlamon said. Jaradat's body was taken for an autopsy in Tel Aviv on Saturday and will be returned to his pregnant wife for burial in their village of Saeer after midday prayers on Monday. His death has inflamed already heightened tensions across the occupied Palestinian territory. On Friday, hundreds clashed with Israeli soldiers in a continuation of months-long demonstrations supporting four hunger-striking Palestinian prisoners held without charge in Israeli jails. On Saturday, nine Palestinians were injured, one critically, when settlers used live rounds of fire in clashes near Nablus. The Hebrew-language media have noted with alarm that the Palestinian Authority is doing little to dissuade protests but is lending its voice to the popular outrage. Issa Qaraqea, the PA's minister for prisoners' affairs, expressed his suspicion of foul play in Jaradat's death. Our information was that Jaradat was being interrogated and then he died. Therefore we call for an international investigation into his death that may have resulted from torture," he told Reuters. As night fell on Sunday, the West Bank showed no sign of calming. In Beitunia, near Ramallah, two teenagers were reportedly hit with live rounds fired by Israeli soldiers. One, the 15 year-old son of the Palestinian secret services chief, was undergoing surgery having been shot in the stomach. "Statements from the international community calling upon Israel to 'respect Palestinian prisoner rights' are insufficient when Israel can arrest, incarcerate and even kill Palestinians without ... consequences for its appalling actions," a statement from the Palestinian leadership read. Without justice, there will be no peace.
