The attacks in London Bridge last Saturday have been claimed by ISIS supporters to have been carried out in revenge for RAF strikes in Iraq and Syria.
This comes after an image of an RAF plane loaded with a laser-guided Paveway missile with the words “Love from Manchester” was written on it and shared online via social media.
It was confirmed genuine by the Royal Air Force in the days after the suicide bombing at Manchester Arena on 22 May that killed 22 people.
Rita Katz, head of Site, a US organisation that tracks the online activity of jihadist and white supremacist groups, said she had spotted a reference to the bomb’s message on pro-Isis social media channels after Saturday night’s van and knife attack in central London.
She wrote on Twitter alongside screenshots from the online groups:
“Pro-Isis channels continue to celebrate London attack as ‘the black days we’ve promised’; ‘the wolves have awakened’ responding to Isis calls,”
One of the images shared by Ms Katz appeared to show the picture of the bomb with the words written on it with the caption:
“This is your merchandise and tonight we responded”.
Isis has claimed responsibility for the terror attack, in which seven people were killed and 49 injured when three men rammed a van into pedestrians on London Bridge before stabbing revellers in bars in the nearby Borough Market.
A statement on the group’s propaganda outlet Amaq said a “detachment” of its fighters had carried out the atrocity.
