Security agents unearthed two caches of bomb-making materials in a northern Bangladesh town after interrogating two suspected members of a banned Islamic group blamed for a series of deadly blasts, an official statement said on Saturday. The members of Jumatul Mujahedeen Bangladesh – which aims to replace the Muslim-majority nation’s secular laws with religious rule – led agents to the caches Friday in Bogra, 176 kilometres north of the capital, Dhaka. The caches included one kilogram of gunpowder, 6.5 kilograms of gel explosives, electric wire, iron balls, electric switches and other material, according to the statement from the Rapid Action Battalion, an elite security force that fights major crimes such as terrorism. They were discovered following the interrogation of suspected militants Ashraful Islam and Abdul Pramanik, who were arrested on Thursday.
