The Home Office has raised the UK threat state to its highest level: critical.
The Government reports that security at UK airports has been increased and extra security measures have been put in place for all flights.
All cabin baggage must be processed as hold baggage and carried in the hold of passenger aircraft departing UK airports. Passengers may take only certain items through the airport security search point, in a single (ideally transparent) plastic carrier bag, such as medicines and tissues. The allowed items are listed on the Home Office website.
