Baghdad, Jan 8, SPA -- U.S. troops launched a pre-dawn raid on Sunday on the headquarters of the influential Sunni Arab Muslim Clerics' Association, which opposes the U.S. occupation, and detained five people, the association said. U.S. troops burst into the Umm al-Qora mosque complex in western Baghdad at 3 a.m. (0000 GMT), blowing doors off hinges and ransacking offices, an association official who declined to be named told Reuters. The U.S. military said it was checking the report. Reuters Television footage showed spent shotgun shells and special explosive charges used to blow out door locks lying on the ground. Many office doors showed signs of forced entry. --SPA 14 41 Local Time 11 41 GMT www.spa.gov.sa/317635
