DHAKA, March 16 (Reuters) - Four suspected militants, including a woman, from a group that has pledged allegiance to Islamic State were killed in a shootout on Thursday when Bangladesh police raided their hideout in the southeast, a senior police official said.
Police said those killed were members of a faction of the Jamaat-ul-Mujahideen Bangladesh group, known as New JMB, which they believe were linked to an attack on a cafe in the capital, Dhaka, last July that killed 22 people, most of them foreigners.
New JMB has pledged allegiance to the Islamic State militant group, which claimed responsibility for the attack on the cafe in Dhaka's diplomatic quarter.
Two policemen were wounded when the militants inside a two-storey building in Chittagong, about 200 km (120 miles) southeast of Dhaka, attacked them with at least a dozen grenades, police official Mohammad Moniruzzaman told Reuters.
It was not clear whether the militants were killed in a shootout with police or had detonated suicide vests they were wearing, Moniruzzaman said.
"The operation is over. Our intelligence and bomb disposal units are now working," he said.
The raid on the building began on Wednesday night and 20 members of seven families trapped inside were taken to safety before the final assault began early on Thursday, Moniruzzaman said. Live bombs were found inside the building, he said.
Bangladesh has been hit by a spate of killings of liberals and members of religious minorities in the past few years.
Police have killed more than 50 suspected militants in shootouts since the cafe attack, including the man they say was its main planner, Bangladesh-born Canadian citizen Tamim Ahmed Chowdhury. (Reporting by Ruma Paul; Editing by Paul Tait)
