A special tribunal in Bangladesh has sentenced a collaborator of the Pakistani army to death for his role in killings during the country's 1971 independence war.

Mobarak Hossain, a former commander of a collaborators' group, was given the death penalty Monday after being convicted of killing 33 civilians in the eastern Bangladeshi district of Brahmanbaria.

He was also separately sentenced to life in prison on a charge of abducting and killing a man during the war.

In 1971, Hossain was a member of Bangladesh's largest Islamist party, Jamaat-e-Islami, which openly campaigned against the creation of Bangladesh, then the eastern wing of Pakistan.

Bangladesh blames Pakistani soldiers and local collaborators for the deaths of 3 million people during the nine-month independence war against Pakistan.
