The group’s Amaq news agency said on Saturday that a Daesh member was behind the attack, but did not provide any evidence.
It added that the attack was made in response to Daesh calls to target countries that have been part of a coalition fighting the group, Reuters reported.
British police on Friday shot dead a man wearing a fake suicide vest who stabbed two people to death in London and wounded three more before being wrestled to the ground by bystanders, in what the authorities called a terrorist attack.
