Police searched trains and passengers in India's financial capital, Bombay, this afternoon after a bomb blast ripped through a packed rush-hour train, killing 12 people and wounding 75.
The attack last night came a day after the 10th anniversary of a wave of bomb explosions in Bombay that killed 250 people. Those blasts were blamed on groups avenging Muslim deaths in Hindu-Muslim riots.
No one has claimed responsibility for the blast, one of a series in the city since last December.
State Chief Minister Sushil Kumar Shinde told reporters the powerful bomb that turned one coach into a mass of mangled metal was made of ammonium nitrate, used in the make explosives and also as a fertiliser.
Usually packed trains and buses were half-empty because of a public holiday on Friday for a Muslim festival. Police checked bags and frisked commuters while guards searched trains.
Police had said 10 people, including three women, were killed in the blast. The toll rose to 12 after two of the wounded died.
