DHAKA, Oct. 16 (Xinhua) -- Two bodies suspected to be militants were found Tuesday after Bangladeshi security forces stormed a hideout of the JMB (Jamaatul Mujahideen Bangladesh) members in the country's Narsingdi district, police said.

Monirul Islam, counter-terrorism unit chief of Bangladesh Police, told journalists that "two suspected JMB members were killed" in the district, east of the capital Dhaka's northeastern region.

Security forces surrounded two buildings in two separate places in the district since Monday night.

After the first operation on Tuesday, "two bodies were found scattered at the first militant den," Islam said.

No further details were immediately available.

Security has been tightened in Bangladesh since militants attacked a Spanish cafe in Dhaka's Gulshan on July 1, 2016, killing 22 people mostly foreigners.

Since the cafe attack, Bangladeshi police have conducted series of large-scale operations against militants.
