The terror plot was to use cartridge bombs to bring down two aircraft over the eastern United States. However, British authorities intercepted the first device at the cargo airport hub after what they described as a “tip-off” from Saudi Arabia. A second device was intercepted aboard a freight plane in Dubai; both aircraft had started their trips in Yemen.
The IoS understands there was a frantic search prompted by “two or three” calls to Saudi Arabia after the tip-off, with security services battling to find the device. French security sources revealed the device was within 17 minutes of detonating when bomb disposal teams disarmed it.
One intelligence source said: “The people in London went back on the phone two or three times to where the interrogation was taking place in Riyadh to find out specifically where the bomb was hidden. There were two Britons there, in immediate communication with where the interrogation was taking place, and as soon as anything happened, they were in touch with the UK. It was all done in real time.”
