Police have arrested at least 120 people, mainly Iraqis and Jordanians, in the nationwide manhunt for those behind the triple Amman hotel bombings, a senior police official said Friday. The police official had no details on the possible role of any of the 120 detained over Wednesday's suicide bombings. "Scores have been rounded up in different parts of the country since the attacks," said the official who spoke on condition of anonymity because he was not authorized to speak to the media. "We don't know if any of them were involved in the attacks or assisted the suicide bombers," the official told The Associated Press. "Many may simply be innocent."
