An Indian court has sentenced five people, including a top Bollywood producer, for their involvement in the 1993 bombings in Mumbai.

Producer Samir Hingora was sentenced to nine years in prison and was given a fine. Hingora was convicted of obtaining weapons from criminals allegedly linked to the attacks, and supplying an illegally procured AK-56 rifle to actor Sanjay Dutt.

The remaining four convicts were given jail terms from eight years to life.

In 1993, 12 blasts in the financial capital's stock exchange and commercial buildings killed 257 people.

One hundred people have been convicted in the bombings, and more than half of them have been sentenced since mid-May.

Two suspected leaders of the bombing plot, Dawood Ibrahim and Tiger Memon, remain at large.

Indian authorities say the attacks were coordinated by Muslims in retaliation for the razing of the Ayodhya mosque by Hindu mobs in 1992, and deadly religious riots between Muslims and Hindus.
