DHAKA: Bangladeshi forces killed four suspected Islamist extremists during raids near Dhaka Saturday, security officials said, the latest clashes in the country’s ongoing crackdown on militants. The elite Rapid Action Battalion (RAB) launched two separate operations Saturday after being tipped off about the presence of Islamist extremists in a building in Gazipur, just outside Dhaka, and a three-storey structure in the northern district of Tangail. “Two extremists were shot dead during a gunfight with the RAB in Gazipur. Weapons and explosives have been recovered,” RAB spokesman Mufti Mahmud Khan told Agence France-Presse. Two more suspected extremists were killed after RAB forces raided another building in Tangail, local RAB chief Mohiuddin Faruqe said. The RAB did not elaborate on the operations and there was no immediate comment about what group the gunmen were affiliated with.
