A Palestinian official said Thursday the results of an autopsy prove that a Palestinian prisoner Israel said had committed suicide actually died of a blow to the head. "We deny it was suicide," said Issa Qaraqe, head of the Palestinian committee for prisoners in a press conference on the fate of Raed Abdel Salam al-Jaabari, 35. The Israel Prisons Service (IPS) had said Tuesday that Jaabari hanged himself in a bathroom at Eshel prison in southern Israel and died en route to hospital. Jaabari's body was taken for autopsies by both Israel and the Palestinians, with Israel **t yet publishing its findings.
