ISIL claimed responsibility for an attack on worshippers at a Shiite mosque in northern Bangladesh that killed one and wounded three others.

The Takfiri group, ISIL (so-called Islamic State in Iraq and Levant) claimed responsibility for an attack on worshippers at a Shiite mosque in northern Bangladesh that killed one and wounded three others.

The attackers entered the mosque in Shibganj, some 200 miles (125 kilometers) north of Dhaka, during early evening prayers on Thursday and opened fire on the gathered worshippers before fleeing.

Television footage showed the heavily guarded Shiite mosque with broken windows and blood stains on the floor.

Police said the muezzin had been killed and three worshippers wounded in the shooting.

The SITE Intelligence Group, which monitors Takfiri activity, said on its website that ISIL had claimed responsibility in a message posted on Twitter on Friday.

Bangladesh authorities have previously said there is no evidence that ISIL militants are active in the country.

However, the group has claimed a series of attacks in Bangladesh, including the shooting and wounding of an Italian priest and the killing of a Sufi Muslim shrine chief, both this month.
