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 88 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 have been willing attackers in what appears to be a technological breakthrough by insurgents. “It’s a sign of their sophistication,” admitted General al-Moussawi, shaking his head. “Now they’re using smart bombs.”
