Three men in Bangladesh have been arrested for allegedly hacking a Hindu man to death over the weekend, the latest in a series of murders by fundamentalists claiming to represent militant groups like the Islamic State of Iraq and Greater Syria (ISIS).

The three suspects in the murder of Nikhil Joarder include a leader from local Islamist group Jamaat-e-Islami and a member of the opposition Bangladesh Nationalist Party, the Dhaka Tribune reports. ISIS had earlier claimed responsibility for the attack.

At least one of those attacks was claimed by Ansar al-Islam, a local offshoot of international militant group al-Qaeda.
