Twenty-nine children were killed and more than 100 others were injured Friday when their day care center caught fire in the northwestern state of Sonora, a spokesman for the state's governor said. The victims were from 1 to 5 years old, said Jose Larrinaga, the spokesman. The fire appeared to have started at 3 p.m. in a warehouse next door to the one-story concrete building that housed the state-run ABC Daycare and spread to the state-run institution, news reports said. By then, many children had already been picked up by their parents from the one-storey building. But others came after the blaze had been put out, with parents screaming their children's names as others fainted. In a message of condolence, President Felipe Calderon wished a quick recovery for the injured, who were taken to several area hospitals. He also called on the nation's attorney general to investigate the fire. Authorities dispatched 15 specialists in reconstruction and three air ambulances to the area along with respirators and specialized medicines, and a U.S. hospital will help treat some of the victims.
