Third car bomb

A four-wheel-drive vehicle crashed into the main terminal at Glasgow airport on Saturday and exploded in flames, a day after police foiled a possible al Qaeda plot to detonate two car bombs in central London.

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 into the 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 wrestled 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.
