Abu Salem, who was convicted under sections of the Terrorist and Disruptive Activities (Prevention) Act or TADA, was sentenced to life in prison. Salem had been tried after his extradition from Portugal.

Convicts Tahir Merchant and Feroz Khan were sentenced to death and a fourth, Karimullah Khan, was also sentenced to a life term, NDTV reported.

The Bombay Stock Exchange, the offices of Air India and a luxury hotel were among about a dozen targets of the March 1993 blasts , which killed 257 people in the deadliest attacks ever to hit India.
