"One of the suicide bombers who blew herself up aboard a crowded Moscow subway car this week was a teenager from the restive republic of Dagestan, Russian authorities said Friday. The national counter-terrorism committee released only the name of the teen who set off her charge in Park Kultury Metro station as Dzhanet Abdurakhmanova, also given as Abdullayeva. But leaks from law enforcement sources filled out the sketch of the 17-year-old's abbreviated, violent life: The girl was the widow of Dagestani militant leader Umalat Magomedov, who was killed by federal troops last year, a source told Interfax news agency. Amid rising public outcry, infuriated officials are pushing hard for culprits to be punished for Monday's twin blasts, which killed 40 people. Another double bombing in Dagestan two days later killed 12 people, most of them police officers.
