In pictures: 1993 Mumbai blasts

There were 12 explosions all over the city. The bombings were believed to have been carried out by one of the city's notorious underworld crime syndicates.

The motive of the bombers is said to have been to avenge the death of Muslims killed in religious rioting in the city during the preceding months.

Most of the bombs were car bombs, but some were placed in scooters. Banks, the passport office, hotels, an airline office, and a major shopping complex were hit.

One of the explosions was near the Mumbai office of the Hindu right wing group Shiv Sena.

Police believe the mastermind of the plot was fugitive underworld don, Dawood Ibrahim, who is thought to be living outside India.

In 2006, a special anti-terror court convicted 100 people for the blasts, including Bollywood actor Sanjay Dutt.

India's Supreme Court has now ruled that Bollywood actor Sanjay Dutt must return to prison for his role in the 1993 Mumbai blasts. The actor has been on bail since 2007 when he appealed against his original sentence of six years.
