Police and witnesses described an SUV-style vehicle in flames being driven at full speed towards the building.
The incident comes with the UK already on alert for terror attacks a day after two cars loaded with explosives were discovered in London.
An eyewitness at the airport speaking to a British TV network said there appeared to be injuries. Images showed black smoke and flames rising from the vehicle just outside the building. Sirens could be heard in the background.
A witness told Sky News that a man had fled from the car as it struck the building and been immediately wrestled to the ground by police.
Police said two people had been arrested, The Associated Press reported.
