A Bangladeshi court has sentenced another 182 border guards to prison for their role in a deadly 2009 mutiny that killed 74 people, mostly commanding officers.

The special court in Dhaka said Monday it handed a maximum seven-year jail term to 20 of the border guards and imposed shorter sentences on the others. Five guards were acquitted.

The latest sentences raise the total number of border guards jailed for the mutiny to more than 3,000. The revolt erupted at the border guards' Dhaka headquarters in February 2009 and spread across the country. Mutineers said they were revolting in protest at low pay and other grievances.

Bangladesh set up special courts to prosecute the border guards, some of whom were charged with murder and arson. Fifty-seven of those killed were army officers.
