MUMBAI, July 11 (UPI) -- A series of explosions ripped through Mumbai's railway system Tuesday killing at least 135 people and injuring hundreds more, according to its police chief.
Seven blasts occurred during the evening along busy rail lines across the city, stirring chaos as the vast majority of commuters returned home, The Times of India reported.
Police officials have placed India's financial capital on high alert as rescuers aid victims and undo the wreckage. There is no word yet as to who was responsible.
The first blast shook a first-class compartment on a local commuter train just after 6 p.m. and six subsequent explosions within the next 11 minutes blew apart trains near railway stations, indicating a well-coordinated attack.
Police Chief A.N. Roy said on Indian television that an estimated 135 people were killed and more than 250 were wounded by the explosions.
"We are busy in the rescue operation. Our first priority is to rescue the injured people," he said.
