DHAKA, March 29 (Xinhua) -- The Bangladesh police have cordoned off two buildings in the country's Moulvibazar district, about 200 km north-east of capital Dhaka, where militants were suspected of being holed up.
According to a Moulvibazar district police official, who did not like to be named, law enforcers had surrounded the houses in two separate areas of the district since early Wednesday.
He said law enforcers retaliated after a grenade was hurled towards them from one of the suspected militant hideouts shortly after it was encircled. None have reportedly been injured in the grenade attack at the security personnel.
No further details were immediately available.
The raid came just a day after Bangladesh Army commandos ended an operation codenamed "Operation Twilight" in Moulvibazar's neighboring Sylhet city.
The assault by army commandos on the militant hideout in the Sylhet city, some 240 km northeast of capital Dhaka ended, killing four militants holed up there.
With the recovery of bodies of the four militants from the hideout, the death toll in the operation stood at 10 as six people, including two policemen, were killed and dozens of others injured in two explosions Saturday in the outer cordon of the siege.
The Islamic State (IS) reportedly claimed responsibility for the blasts.
Security has been tightened in Bangladesh after militants attacked a Spanish cafe in Dhaka's Gulshan on July 1, which left 22 people, mostly foreigners, dead.
