The Bangladesh Muktijuddho Mancha held a rally at the altar of the Raju Memorial sculpture on the Dhaka University campus on Monday to press home the demand.
The delegation was led by Barrister Turin Afroz, sculptor Rasha, Bangladesh Muktijuddho Mancha's Presidet Aminul Islam Bulbul and General Secretary Md Al Mamun.
Turin called on Pakistan to 'immediately apologise' for the genocide and massacre of Bangladesh's intellectuals in 1971. "Otherwise we will file a case against Pakistan in the International Court of Justice for genocide," she said.
"Instead, they had a big hand in the assassination of Bangabandhu in 1975. They were also involved in the grenade attack on Aug 21 [2004]. The grenades came from Pakistan. The Pakistan embassy is still conspiring to undermine the Liberation War. I urge the government to increase surveillance of the embassy."
