Bangladesh’s elite anti-terrorism unit detained on Sunday three suspected members of a militant group believed to be behind a spate of recent attacks in the south Asian country.

Muslim-majority Bangladesh has seen a rise in Islamist violence in which liberal activists, members of minority Muslim sects and other religious groups have been targeted.

The detainees were members of the banned Jamaat-ul-Mujahideen Bangladesh and were arrested in a raid conducted in the northwestern district of Rajshahi, said Rumman Mahmud, a deputy director of the Rapid Action Battalion.
