Heathrow terminal reopens after security scare
London, July 4: London's Heathrow airport reopened a busy international terminal today after a security scare led to the cancellation of around 55 flights.
Thousands of passengers were evacuated from Terminal 4 after a suspect bag was found shortly before midday (1630 IST), the airport's operator BAA, a unit of Spanish infrastructure and construction company Grupo Ferrovial, said.
Police also ordered the evacuation of the departure lounge so that all passengers could be searched a second time.
The terminal reopened shortly after 5 p.m.
Flights arriving at the terminal, which handles only international flights, were not affected.
British Airways said it had cancelled all its European departures from the terminal for the day, as well as all long-haul flights due to depart between 3 p.m. and 9 p.m. and 2000 GMT (1930 and 0130 IST).
An airport spokesman said passengers due to fly from the terminal today evening should check their flight with their airline.
Britain's security threat level has been set at ''critical'' since two car bombs were found in central London on Friday and members of a suspected al-Qaeda cell attacked an airport in Scotland on Saturday.
Eight suspects have been arrested in Britain and Australia.
