Islamic State claimed responsibility of yesterday's murder of a Christian convert in Kurigram, "terror monitoring" body SITE Intel Group said.

Hossain Ali, 68, a freedom fighter and a retired inspector of the government's family planning department, was killed by miscreants yesterday morning.

The attack came a week after a Shia homeopathic doctor was killed in Jhenaidah and a Hindu priest killed in Panchagarh – both of which were works of IS as claimed by SITE.

SITE Intel Group is the only link between the murders and Islamic State so far.

Bangladesh authorities, however, have repeatedly denounced the existence of Islamic State in the country.
