A military investigative judge charged a Lebanese-American man with murder and torture of Lebanese citizens on Tuesday, crimes he allegedly committed during Israels occupation of southern Lebanon, judicial officials said. The accusations could carry a death sentence. Amer Fakhoury is accused of working as a senior warden at Khiyam Prison, which was run by an Israel-backed Lebanese militia. The prison has been described by human rights groups as a center for torture. He was detained in September after he returned to his native Lebanon from the US, and Lebanons intelligence service says he confessed during questioning to being a warden. However, Fakhourys lawyer and family in New Hampshire say that, while he was indeed a member of the so-called South Lebanon Army, they insist he had no direct contact with prisoners and was never involved in the interrogation or torture of prisoners. Fakhoury, 57, is also undergoing cancer treatment, and it remains unclear if hell be able to stand trial. The restaurant owner from Dover, New Hampshire became a US citizen last year. The Lebanese judicial officials said Tuesday that the judge, Najat Abu Shakra, referred Fakhoury for trial in a military court. No date was set for the tribunal. The officials spoke on condition of anonymity because they were not authorized to speak to the media. The officials said Abu Shakra charged Fakhoury with "murder and attempted murder of prisoners inside Khiyam Prison as well as kidnapping and torture." The prison, run by the SLA, was abandoned after Israeli forces pulled out of southern Lebanon in 2000, ending an 18-year occupation. Human rights groups have said in the past that Khiyam Prison was a site of torture and detention without trial. Israel denies the allegations. However, Fakhourys lawyer and family have said he was never named when extensive investigations of Khiyam Prison were conducted years ago. His family said that, as a former member of the SLA, he was charged alongside many others with collaborating with Israel. That charge was dropped in 2018, they said. US Sen. Jeanne Shaheen of New Hampshire began drafting sanctions legislation against Lebanese officials last month in order to push for Fakhourys release. The charges by the investigative judge were separate from a lawsuit against Fakhoury filed by former inmates at Khiyam Prison. He is being questioned in that case about alleged human rights abuses. The questioning was supposed to take place on Monday, but was postponed until Feb. 17 because Fakhoury is undergoing chemotherapy. Fakhoury’s family said doctors have said his condition is life threatening. In addition to an infection and a bleeding disorder, doctors believe hes developed an aggressive form of lymphoma. Hundreds of former Lebanese members of the SLA militia had fled to Israel, fearing reprisals if they remained in Lebanon. Others stayed and faced trial, receiving lenient sentences. Fakhourys lawyer and family say he fled Lebanon in 2001 through Israel and eventually to the US.
