LONDON - A major terrorist plot to blow up an aircraft mid-flight between Britain and the U.S. has been disrupted, police said Thursday.
Police arrested a number of people overnight in London after a covert counter-terrorist operation lasting several months, police said in a statement.
The plot was believed to have involved smuggling explosive devices on board an aircraft in hand luggage, police said. It was likely to target flights from Britain to the U.S., police said.
British Airways advised passengers on its Web site Thursday that no hand luggage was to be permitted on any aircraft leaving Britain.
Liquid explosives, were to be used.
