The Islamic State claimed responsibility on Saturday for the Friday London Bridge knife terror attack where two people were killed and three wounded, according to Reuters.

The Islamic State’s Amaq news agency said it was one of its soldiers who carried out the attack, but it hasn’t offered any proof.

The attack a result of a call to action by the Islamic State to target the nations in the coalition fighting against the Islamic State, it said.

The attacker, 28-year-old Usman Khan was known to police before the attack, as he had a criminal record that included acts of terrorism.

Khan was previously part of a group of men charged in 2010 with plotting to attack the London Stock Exchange and later pleaded guilty to trying to raise money to build an Arabic educational institution in Kashmir that would provide firearms training.
