Those cagey jihadists have been foiled once again by our good friends at the MI5!

A terrorist plot to blow up planes in mid-flight from the UK to the US has been disrupted, Scotland Yard has said.

It is thought the plan was to detonate explosive devices smuggled on aircraft in hand luggage.

Police have arrested about 18 people in the London area after an anti-terrorist operation lasting several months.

Security at all airports in the UK has been tightened and delays are expected. MI5 has raised the UK threat level to critical - the highest possible.

According to MI5’s website, critical threat level means “an attack is expected imminently and indicates an extremely high level of threat to the UK”.
