LONDON: A terror plot to attack four cities across Britain was foiled by the authorities after they intercepted two foreign airline pilots, believed to be sympathisers of ISIS, discussing the targets, a week after the Paris terror attacks.
The two commercial airline pilots, one of whom was flying for an airline on an intelligence service watchlist, were intercepted talking about the plot and the information passed on to Britain’s spies at the Government Communications Headquarters (GCHQ).
The intercept took place in the week after the Paris terror attacks last November, the Sunday Express reported.
Although they used coded messages from the cockpits of their passenger jets, GCHQ used the Arabic transcripts to established they were talking about attacks on London, Bath, Brighton and Ipswich.
The uncovering of the plan raised the terror alert in the UK and was one factor which led to Operation Templer, involving 10,000 soldiers being deployed to support police on Britain’s streets in the wake of the Paris attacks on November 13 last year which claimed 138 lives.
“The areas we believed these attacks might take place were given extra surveillance. Troops were on several hours notice to deploy as part of Operation Templer,” a senior intelligence source was quoted as saying by the newspaper.
“Alarm bells rang after several communications in code involving overseas airline pilots were picked up by chance. We can only assume that they considered it safer to use this frequency than other modes of communication”.
“We immediately passed these to the security services who then asked us to monitor certain airlines entering UK airspace,” the source said.
The conversation was intercepted by Royal Air Force (RAF) operators based at the National Air Traffic Services (NATS) Control Centre in Hampshire, on the southern coast of England.(agencies)
