Updated from 11:40 a.m. Seven explosions rocked Bombay train stations Tuesday during the Indian financial center's evening rush hour, the Associated Press reported. Bloomberg, citing police, said 163 people have been killed and more than 450 injured. The AP reported that the bombings were preceded by a series of grenade attacks a few hours earlier in Kashmir, a region over which both India and Pakistan claim jurisdiction. Islamic militants launched the grenade attacks, according to the report, and killed eight people.
