Islamic State militants claimed responsibility for the London Bridge attacks on Sunday.

The terror group, which had been hailing the carnage throughout the day on its online accounts and anonymous message boards, said its fighters carried out the rampage, according to Site Intelligence Group, which tracks the web activity of jihadist organizations.

“Crusing #brits now living in a state of terror and fear! Where is your great Kingdom now? #LondonBridge,” said one post shared by Site’s director, Rita Katz.

Another missive included the iconic image of the Royal Air Force bomb with “Love from Manchester” written on it — referring to the recent attack on the Ariana Grande concert and adding that the weapon “is your merchandise, and tonight we responded.”

The attack on London came just a few hours after Islamic State’s Nashir News Agency called for followers to “Kill the civilians of the Crusaders” with guns, knives and trucks, according to the Telegraph.

“Run over them by vehicles,” the agency said in a post. “Gain benefit from Ramadan.”
