(Two mentally retarded)Female Bombers Strike Markets in Baghdad

BAGHDAD — Remote-controlled explosives strapped to two mentally retarded women detonated in a coordinated attack on Baghdad pet bazaars Friday, police and Iraqi officials said, killing at least 73 people in the deadliest day since the U.S. sent 30,000 extra troops to the capital this spring.

The chief Iraqi military spokesman in Baghdad, Brig. Gen. Qassim al-Moussawi, claimed the female bombers had Down syndrome and that the explosives were detonated by remote control, indicating they may not having been willing attackers in what could be a new method by suspected Sunni insurgents to subvert stepped up security measures.
