Jordanian police have foiled a planned suicide attack by al-Qaida and arrested two Iraqi militants and a would-be Libyan bomber, Jordanian officials said Wednesday. Police are also searching for three more Iraqis and a Saudi believed to be part of the terror cell, an unidentified Jordanian security official told the state-run Petra news agency. Government spokesman Nasser Judeh said the militants planned to attack a "vital civilian facility" in Amman but declined to further describe the target. Judeh told The Associated Press that police made the arrests after recently obtaining certain "intelligence." He declined to provide further details. "Our security forces succeeded in foiling a terrorist plot organized by the al-Qaida terrorist group involving people of Iraqi, Libyan and Saudi nationality," the unidentified official said. The official identified the three detainees as Mohsen Mathloom Alousi and Abdul Karim al-Jumaili, both Iraqis born in Baghdad, and the intended suicide bomber Mohammed Saeed al-Darsi from Libya. The three have not yet been charged and would face a State Security Court hearing soon, the official added. Police are hunting several other terrorists, including a Saudi Arabian citizen identified as Turki Nasser Abdullah, and three more Iraqis, Saad Fawzi al-Obeidi, Youssef Abdul-Rahman al-Obeidi and Saad Fakhri Younes al-Nueimi.
