Quasem is the sixth war criminal and fifth Jamaat leader executed for war atrocities.
He played a key role in founding the al-Badr militia, which along with other collaborators tried to prevent the birth of Bangladesh and killed innocent civilians.
The ‘Bangali Khan’ – a moniker that Quasem earned for his enthusiastic brutality on behalf of the Pakistani junta – was found guilty of abduction, confinement, torture and murder during the Independence War.
He was handed down the maximum penalty by a special tribunal in 2014. He was also given a total of 72-year imprisonment on eight other charges of abduction, conspiracy and planning.
Quasem had spent a huge sum of money to appoint a US lobbyist to make the war crimes tribunal controversial. But all his efforts were wasted after the top court threw out his appeal to review his sentence on August 30.
