Pounding monsoon rains in Bombay and its suburbs killed at least nine people who were trapped in cars, drowned or were crushed by falling walls, police and a news report said Wednesday. Two boys died in overflowing sewage lines in the Marol-Maroshi suburb and three other people died when walls of their homes collapsed in the Kandivli and Damupada areas, the Press Trust of India news agency reported. Two other people drowned in gushing waters elsewhere in the city. Police said three people _ a man and his elderly parents _ were found stranded in their car in the Santa Cruz area. Police were able to revive the mother and son but not the father, a police officer said. The officer, who declined to be named, said the man apparently died from carbon monoxide poisoning. Santa Cruz received the heaviest rain of more than 94 centimeters (37 inches) on Tuesday. Another death was reported in a car elsewhere in Bombay, police said. Walls also collapsed in several other parts of the city but there were no immediate reports of casualties, PTI said.
