DHAKA: Bangladeshi security forces have detained four suspected members of a banned Islamist militant group who were believed to be planning attacks on celebrations of the traditional new year, a police official said on Wednesday. Muslim-majority Bangladesh has seen a surge in Islamist violence over the past couple of years, targeting liberal activists, as well as members of minority Muslim sects and other religious groups. The four members of Jamaat-ul-Mujahideen Bangladesh were arrested in an overnight raid in Mymensingh, 115 km from the capital, Dhaka, said police official Mohammad Harun-ur Rashid. A large quantity of bomb-making material was seized and the suspects were believed to have been planning to target celebrations of the Bengali New Year on April 14, he said. At least five Jamaat-ul-Mujahideen members have been killed in shootouts since November, as authorities have intensified a crackdown on militants trying to establish an Islamist state.
