Terminal at London’s Heathrow Evacuated

Terminal 4 at Heathrow airport in London has been evacuated following the discovery of a suspicious bag. And authorities now believe that al Qaeda sent at least a dozen people to infiltrate the British National Health Service.

Thousands of passengers were evacuated from Heathrow's busy Terminal 4 today in new terror alert after a 'suspect bag' was discovered inside.

It brought more chaos to the terminal which is British Airways' main hub as officials warned of more delays.

Airport operator BAA said they were in 'lock down mode.'

Passengers just moments from boarding were turned back from their flights after the alarm was raised at around 1pm

Planes with passengers already on board were directed away from the terminal.

All passengers inside the building were ordered to evacuate the terminal immediately as police and security services dealt with the 'suspect bag.'

A spokesman for BAA said: "In response to a suspect bag in Terminal 4, secondary searches are now being carried out on departing passengers. This will cause some delays to flights.

"Contingency plans have now been activated to ensure that we are able to effectively manage the increase in resource that this secondary search requires. We are working with the police to bring a swift resolution to the incident."

British Airways said it was monitoring the situation.

Meanwhile, up to 12 members of Al Qaeda were sent to work in the NHS, security sources said today.

Eight people have so far been arrested in the hunt for the car bombers who tried to cause carnage in London and Glasgow. Six of them are NHS doctors.

The scale of the infiltration by the terror network has led police to believe several members of the gang are still at large and the threat of an atrocity remains high.

Things are going to be jittery in Britain for a while until they catch most or all of the plotters from this particular group.
