A Hamas preacher died in the custody of the Palestinian intelligence service, and his family, citing reports from fellow detainees, alleged Saturday that he had been tortured. Majed Barghouti, 44, died at an intelligence lockup in the West Bank city of Ramallah on Friday, a week after his arrest. Palestinian President Mahmoud Abbas ordered an investigation of the death, which came among repeated complaints by Hamas detainees that they were mistreated by Abbas' forces. Hamas denounced the death as a crime. In a statement published in Palestinian newspapers, the intelligence service said Barghouti had complained of chest and abdominal pain and was examined by a hospital doctor two days before his death. Intelligence officials were not available Saturday to comment on the torture allegations.
