The terrorist group has announced that it is taking responsibility for the attack on Friday in London, Interfax reported.

The group published a corresponding message on its resources on the Internet, while not providing any evidence that the author of the attack is really an ISIS member.

On November 29, the 28-year-old Usman Khan carried out a knife attack, leaving two people killed and three injured. Khan was previously tried for terrorist crimes, but was prematurely released from prison.
