Two British Islamic State fighters have threatened terror attacks on Heathrow, Gatwick and Downing Street in a chilling video celebrating the Brussels bombings.
The men, wearing black masks and speaking with London accents, filmed themselves laughing at the Belgium atrocity before posting their message on Instagram.
One of the men proclaims: ‘Belgium, Brussels airport big boom went off…innit. Heathrow…’
They are feared to have been trained by Birmingham cyber-hacker Junaid Hussain, a major recruiter for ISIS.
