Five Jordanian men pleaded not guilty Monday to charges of receiving secret information from the radical Palestinian group Hamas that could jeopardize Jordan's safety. Jordan's military prosecutor said during the trial's opening hearing that Hamas provided the alleged militants with military training in an unnamed neighboring country and tasked them with monitoring military installations and the Israeli Embassy in Jordan. The defendants, two of whom are of Palestinian origin, were identified in the prosecutor's charge sheet as Thabet Abul-Hajj, 37, Salim al-Hosani, 27, Azzam Ahmed Jaber, 36, Mohammed Rabee al-Khojah, 43 and Talib Hassan Abdullah, 46. The men allegedly succeeded in monitoring military sites on Jordan's borders with Israel and Syria and sent the information back to Hamas members, according to the charge sheet. If convicted, the men could be sentenced to up to 15 years in jail.
