A little-known Islamic terror group that claimed responsibility for Bombay's train bombings warned of more attacks Tuesday, as investigators questioned Muslim preachers in India's remote northeast about the blasts. The death toll in the July 11 attacks, meanwhile, rose to 207 from 182 when officials added people who died after being taken to hospitals in Thane, a town outside Bombay. "All of them are blast victims," said B.M. Raut, a disaster management official in the state government of Maharashtra, where Bombay is located. While police are still trying to determine who carried out the well-coordinated attack, an outfit calling itself Lashkar-e-Qahhar said in an e-mail to a local television station that 16 people took part in the bombings in Bombay - also known as Mumbai - and that one was killed. But "all the remaining 15 ... are totally safe, and celebrating the success of this mission and also preparing for the next mission," said the e-mail, written in poorly punctuated, often ungrammatical English.
