The U.S. military in Iraq suffered its deadliest month since last year's invasion with more military personnel killed in action in November than in any equivalent period, the Pentagon's figures show.

At least 135 combat deaths were reported in Iraq between 10 a.m. New York time on Oct. 29 and the same time on Nov. 30, according to the casualty toll posted on the Department of Defense Web site. That surpasses the toll from April this year, when 131 soldiers, Marines and other military personnel were killed between March 31 and April 30, the Web site showed.

More than 50 of November's deaths occurred during the U.S. and Iraqi offensive to recapture the city of Fallujah, west of Baghdad, from insurgents. That operation reduced parts of the mainly Sunni Muslim city to rubble and, according to the military, left more than 1,200 rebels dead.
