The 70-year-old imam of the mosque was killed and three other people injured when three gunmen opened fire on worshippers during prayers at the mosque last night.

Three gunmen opened fired as Shia Muslims were offering evening prayers at a mosque in Shibganj area of Bogra district.

The assailants fled the scene crossing a wall after locking the mosque's main gate from inside apparently to prevent people in the neighbourhood to come to the rescue of the victims, sources said.

The attack comes after a rare pre-dawn bomb attack on a Shia procession in Bangladesh's capital that killed one person and wounded 80.

The attack on the procession on October 24 was allegedly carried out by the militant group Jamaatul Mujaheedin Bangladesh, police said.

Prime Minister Sheikh Hasina in a statement after the Bogra attack said those who raided mosques were not 'true Muslims' while she ordered law enforcement agencies to launch a probe into the incident.
