Dhaka, March 24 (IANS) Bangladesh police on Friday cordoned off a building in the country's Sylhet city, suspecting presence of militants.
According to a police official, law enforcers had surrounded the five-storied building since Thursday.
Several gunshots and explosions were heard from the spot. Law enforcers retaliated after a grenade was hurled towards them from the house, Xinhua news agency reported.
According to police, the militants rented a flat in the building three months ago.
The raid came days after four militants were killed when the law enforcers stormed a militant hideout in Sitakunda on the outskirts of Chittagong.
Since the Holy Artisan Bakery attack here, law enforcers have gone tough against Neo-JMB (an offshoot of the banned militant outfit Jamaatul Mujahideen Bangladesh) which is blamed for the July 1 last year attack.
At least 20 hostages, mostly foreigners, were killed in the attack.
