GLASGOW, Scotland, (Reuters):

A four-wheel-drive vehicle raced across a central reservation and rammed into the front doors of Glasgow airport's main terminal yesterday before exploding in flames, Glasgow police and witnesses said.

A Glasgow police spokeswoman said there were no immediate reports of any injuries and said the blaze was under control.

Witnesses told the BBC that the vehicle, a Land Rover or a Jeep Cherokee, had exploded shortly after crashing intothe glass front doors of the terminal, and said there was a heavy stench of petrol.

"It raced across the central reservation and went straight into the building," said taxi driver Ian Crosby outside the terminal.

Crosby said a stocky Asian man had got out of the car and was quickly tackled to the ground by bystanders.

"It would appear to me to have been a deliberate attack. I think this was a terrorist attack," Crosby said.

Four arrested

A separate witness told Sky News that a man had attempted to take a gas cylinder from the car before the vehicle went up in flames, but that could not be independently confirmed.

Sky quoted Glasgow police as saying four people had been arrested in the wake of the incident. The attack came a day after police in London foiled a plot involving two car bombs packed with fuel, gas canisters and nails that were parked in central London on Friday night and set to detonate.

Anti-terror police said the car bombs could have killed or maimed scores of people. A large-scale counterterrorism operation has been launched in the wake of the thwarted plot, which came less than two years after 52 commuters were killed in a series of suicide bomb blasts on London's transport system.

In Glasgow, another witness told the BBC he was not sure that the car was intended to be a bomb as the explosion that occurred after it crashed was relatively small.
