Bangladesh detained three suspected members of a banned militant group, police said on Sunday, as security forces step up a hunt for militants behind a spate of recent attacks.
Bangladesh has suffered from a wave of extremist violence, with two foreigners, four secular writers and a publisher killed this year. Some of the attacks have been claimed by Islamic State.

The three men, who were active members of the banned Jamaat-ul-Mujahideen, were caught in an overnight raid in the capital, Dhaka, Monirul Islam, a police joint commissioner, told reporters, as the handcuffed men were paraded before the media.
A mobile phone network jammer and books were found in their possession, Islam said. Preliminary investigation showed the jammer was used during meetings to avoid leaking information, he said.
The group was believed to be behind a series of recent attacks, including bombings of a Shia shrine and the killing of a policemen, police said.
Tension has been rising in Bangladesh since Prime Minister Sheikh Hasina launched a crackdown on militants, putting several leaders on trial for war crimes committed during the 1971 war of independence.
