Mumbai, India (AP) - Seven explosions ripped through packed commuter trains during rush hour Tuesday in India's commercial capital, killing more than 100 people and injuring 300 in what officials said was a well-coordinated bomb attack by terrorists.
India's major cities were put on high alert after the blasts, which appeared timed to impose maximum carnage on the bustling city of 16 million. Its crowded rail network was thrown into chaos by the blasts and authorities were struggling to determine the impact.
