Sector commander Abu Osman Chowdhury breathed his last at the Combined Military Hospital (CMH) at around 8:00am while undergoing treatment.
He was 85.
His personal secretary Abul Bashar confirmed the news to The Business Post.
Abu Osman, who served as the commander of sector-8 during the Liberation War, tested positive for Covid-19 on August 30.
Later, the war hero was rushed to CMH as his condition deteriorated.
Osman, who won the Independence Award for his contribution to Bangladesh’s freedom, had been suffering from old-age complications for a long time.
Osman played a key role in the formation of Ekattorer Ghatak Dalal Nirmul Committee, which was formed to demand justice for the 1971 war atrocities.
