A court in India has sentenced 11 people to life in prison for their roles in a notorious massacre during the 2002 anti-Muslim riots in Gujarat.

Twelve others convicted in connection with the so-called Gulbarg Society killings were jailed for seven years by the special court in Ahmedabad.

In the attack, 69 people were hacked and burned to death by a mob.

More than 1,000 people, mostly Muslims, died in the riots, sparked by a fire on a train that killed 60 Hindu pilgrims.
