The Indian city of Bombay is struggling back to its feet the day after a series of deadly bomb blasts hit packed commuter trains at evening rush hour. As the death toll nears 180 and the number of injured rises above 600, there has still been no claim of responsibility for the attacks.

Investigators searched the twisted wreckage of train cars for clues Wednesday, hoping to learn who was responsible for planting eight bombs that tore through Bombay's commuter trains a day earlier.

Overwhelmed hospitals struggled to cope with the flood of injured. Many people went from hospitals to morgues hunting for missing relatives.

But less than 24 hours after the blasts, the bustling city resumed a measure of normal life. The stock markets opened, and services on the damaged rail network were partly restored. Some stayed away from the trains, others accepted the risks fatalistically.

"Either today or tomorrow, day after, you have to step out…Nothing really stops Bombay," said one citizen.

"Life has to go on," said another.

No one has claimed responsibility for the blasts, but suspicion has fallen on Islamic militant groups waging an insurgency in Indian Kashmir.
