London: The Islamic State group said on Thursday one of its “soldiers” carried out the deadly rampage at the British parliament, as Prime Minister Theresa May vowed the nation would not be cowed by its deadliest attack in 12 years. “We are not afraid and our resolve will never waver in the face of terrorism,” she said. ISIS said it was responsible for the London murders, according to the Amaq propaganda agency, the first time the jihadists have claimed an attack on British soil.

“The perpetrator of yesterday’s attack in front of the British parliament was a soldier of the Islamic State and the operation was carried out in response to calls to target coalition countries,” Amaq said citing a “security source.” Police in London said there was “no prior intelligence about his intent to mount a terrorist attack.” Britain is a member of the US-led coalition fighting ISIS.
