Sunday's death of Palestinian bus driver Youssef al-Ramouni quickly touched off Palestinian stone-throwing protests and a general strike in some Arab neighborhoods of Jerusalem, pouring more fuel on tensions.In the Abu Dis neighborhood of Jerusalem, shops closed after news of Ramouni's death and masked youngsters blocked roads with dumpsters. Dozens of youths threw stones at Israeli soldiers, who fired tear gas.In the video, youths can be seen burning tires, and using a hammer to break through the barrier which cuts through the town.Ramouni's brother Louy told Reuters there was no way that Youssef, the father of two young children, would have killed himself. "I saw the body last night and I saw bruises and marks that he was beaten up," he said.His father said,"The signs on his body do not show that he wanted to commit suicide. Thank God, he wasn't sad and he never had any problems in his life that would have brought him to commit suicide."Israeli police said an autopsy would be conducted. Ramouni's family requested a Palestinian pathologist be present but it was unclear whether this would be allowed.
