Militants of the Islamic State claimed responsibility for the attack in Dhaka, the capital of Bangladesh, and threatened  with new attacks.

Islamic State has now released a video calling for jihad in Bangladesh, Dhaka Tribune reported.

The video message believed to be issued from Raqqa in Bangla was first found in an IS-affiliate website and then released on YouTube early Wednesday.

Dreadful attack in a restaurant in the diplomatic district of Dhaka last Friday killed at least 22 people including 17 foreigners.
