After nearly 13 years of trial, a special court on Tuesday held 49 accused guilty in 2008 serial blasts in Ahmedabad that claimed 56 lives.
The court acquitted 28 others. Out of these, 16 were given benefit of doubt and the rest were pronounced innocent due to lack of evidence.
Special Judge A.R. Patel delivered the verdict. The quantum of punishment will be announced on Wednesday.
Statements of over 1,100 witnesses were taken in the case. The accused have been lodged in various jails in the country.
The trial began in December 2009 against 78 people connected to the banned terror outfit Indian Mujahideen. The number of accused later came down to 77, after one of them turned approver.
Fifty-six people were killed and over 200 injured in 21 synchronised blasts that rocked the Gujarat city in a span of 20 minutes on July 26, 2008.
Indian Mujahideen, had claimed the responsibility for the blasts and had termed it as an act reprisal for the 2002 riots.
More than 1,000 people, mostly Muslims, had lost their lives in Gujarat in the post-Godhra riots that erupted after 59 kar sevaks, returning from Ayodhya, were burnt alive on board the Sabarmati Express in Godhra.
