Jordan says an investigation into the deadly bombings against three Amman hotels has concluded that al-Qaida in Iraq was behind the attacks. "The investigation has arrived at the conclusion that al-Qaida was behind the attacks and specifically Abu Musab Al-Zarqawi's group," Deputy Prime Minister Marwan al-Muasher told a news conference on Saturday, adding that all three attackers were "non-Jordanian males".The statement contradicts al-Qaida in Iraq which said four Iraqis - including a husband and a wife - carried out Wednesday's attacks against the Grand Hyatt, Radisson and Day's Inn hotels that killed 57 people, including the bombers. There was "no indication of a woman among the bodies of the perpetrators", Muasher said.
