Britain has issued a total flight ban in an unprecedented move on a teenager over fears he might be a suicide bomber.
Every airline that flies directly to the UK - which is at least 150 - has been instructed to bar 18-year-old Redar Taher Masouf from flying.
The Libyan-Algerian is an al-Qaeda sympathiser who came to the attention of the MI5 during an investigation into Islamic extremism in Manchester.
Masouf's father claimed asylum here 18 years ago, but he Masouf himself left Britain a year ago after his indefinite leave to remain was revoked.
A British intelligence source told The Sun: 'A blanket ban like this has never been issued before, although terror suspects have been barred from particular flights.
'The security services' assessment was that he constituted a potentially dangerous threat. Someone with this intelligence profile might become a suicide bomber.'
