The Islamic State group has claimed responsibility for the killing of a homeopathic doctor from the minority Shia community in southwestern Bangladesh, according to a US-based monitoring group.
Unidentified assailants stabbed 45-year-old Abdur Razzak at Kaliganj in Jhenaidah district on Monday night while he his way home from his chamber.
Anwar Hossain, the chief of the local police station, said authorities had no clues about who attacked Razzak and why. His family said Razzak had no known enemies but had received a phone call demanding money.
The SITE Intelligence Group, which tracks jihadi organisations, said on Tuesday the IS had claimed the killing.
Shias are a minority in Sunni-majority Bangladesh, and members of the community have been attacked in the past.
The IS has claimed responsibility for several attacks in recent months but this has been rejected by the government, which said local militant groups were behind the incidents.
Some media reports on Tuesday said Razzak was originally a Sunni Muslim but was influenced by the Shia doctrine and often visited members of the community and participated in prayers with them.
