The chief minister of the Indian state of Gujarat, Narendra Modi, has been summoned to appear next week before an inquiry into devastating riots in 2002.

Mr Modi faces questions over the murder of Congress MP Ehsan Jafri.

The Gujarat authorities were criticised for not doing enough to prevent the violence. Mr Modi denies wrongdoing.

More than 1,000 people, mostly Muslims, were killed in the riots after 60 Hindus died in a train fire. The fire's cause was never clearly established.

Hindu groups allege the fire was started by Muslim protesters, but an earlier inquiry said the blaze was an accident.

In the violence which engulfed the state, Mr Jafri and dozens of others were killed in a residential complex in Ahmedabad known as the Gulbarg Society.
