UK airports alert as US warns of new bomb threat

The deputy prime minister made the warning amid fears that terrorists are working on a bomb that could sidestep current measures.

He said: “This is the world we now live in, this will not be the last time there are adjustments made because we are having to constantly evolve our own defences in response to ways that people want to attack us.
