DHAKA, Sept. 6 (Xinhua) -- Members of Bangladesh's anti-crime elite force Rapid Action Battalion (RAB) have battled to neutralise militants holed up in a building rocked by fresh explosions in capital Dhaka.
Fresh sounds of intermittent gunshots and explosions were heard Tuesday night, indicating the militants' denial to surrender finally.
At least three heavy blasts were heard from inside the six-storey building since about 9:00 p.m. local time Tuesday night.
A huge blast inside the building tilted it towards one side. Thick smoke is seen to billow from the building.
At least four RAB personnel were injured due to the blasts.
It's unclear who were firing the shots as RAB prepared for a final assault following the militants' indication not to surrender.
A ban has been enforced barring entry of ordinary people within the vicinity of the building as final preparations were underway to flush the militants out from their den.
RAB early Tuesday cordoned off a building in capital Dhaka, where militants were suspected of being holed up.
"The militants have agreed to surrender," RAB spokesman Mufti Mahmud Khan told reporters Tuesday evening. He did not tell immediately when they will surrender.
Law enforcers had surrounded the six-storey house in Dhaka's Mirpur area since early Tuesday.
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.
