An Indian court on Wednesday found 31 people guilty of killing 33 victims in a single house.
The convicts set a building on fire in Gujurat state during one of India's worst rounds of communal violence nine years ago.
For several weeks in 2002, mobs rampaged through minority neighborhoods, towns and villages in the state. Rioting sparked when a train was set ablaze and 60 pilgrims were burnt alive. Extremists blamed the train attack on minorities.
Mobs hungry for revenge rampaged through towns and villages across Gujarat state during three days of bloodshed.
Wednesday's verdict dealt with an arson attack on a building in Mehsana district, nearly 25 miles north of Ahmadabad, the main city of Gujarat state. Thirty-three victims, including 20 women, who had taken shelter there were burned to death in the fire.
Judge S T Srivastava acquitted an additional 41 suspects of murder charges for lack of evidence.
The judge will sentence those convicted later this week. They face the death penalty.
Two of the suspects died during the trial, which had been expedited by orders from India's top court, the Supreme Court.
