Security forces said the militants had blown themselves up at their Shibnagar hideout on Thursday, a day after law enforcement agencies laid siege to it.
A woman, Sumaiya Begum, believed to be Abu's wife, had surrendered with a four-year-old girl Wednesday afternoon.
Shibganj upazila Nirbahi Officer Shafikul Islam said they had imposed a restriction on movement which would be in effect until further notice.
The government intensified its anti-terrorism operations after last July's Dhaka cafe attack in which 22 people, including 17 foreigners, were killed.
Police have since compiled a list of nearly 5,000 suspected militants. A number of leading militant figures have since been killed in counter-terrorism raids across Bangladesh.
