MUMBAI, India (AP) -- India's home affairs minister says investigators have no immediate leads as to who was behind the triple bombing in the city of Mumbai that killed 17 people.
Palaniappan Chidambaram told a news conference Thursday that the blasts in three separate neighborhoods were "a coordinated terror attack."
He says the bombs were made of ammonium nitrate and were not remotely triggered.
He says there were no immediate leads as to the culprits.
He also says there were no intelligence warnings of a possible attack.
He lowered the casualty toll to 17 confirmed deaths and 131 injuries. He said a severed head was found that could be an 18th casualty. He did not explain the discrepancy from an earlier government statement that confirmed 21 deaths.
