Passengers have been evacuated from Heathrow Airport after a serious accident.
Emergency teams have been rushed to the scene after the incident which happened around 8am at Terminal 5.
Hundreds of people have been stuck on their planes, and many have complained of confusion and delays.
Heathrow Airport said in a statement: “We are dealing with a serious accident involving two vehicles on the airfield.
“We are working closely with the emergency services and updates will follow. The airfield remains open and we will work to minimize disruption to our passengers’ journeys.”
The airport confirmed the incident on Twitter and said it is unlikely to cause delays.
Hi Alaistair, following an incident on the airfield involving two members of staff, an investigation is underway and we are working with the Police. This incident didn’t involve any passengers and is not expected to cause any impact on journeys today.

However, passengers have complained that they have been delayed.
One Twitter user wrote: “Apparently there has been an accident on one of the runways at @HeathrowAirport and many planes (including this one) are parked on the apron with unspecified delays of ‘hours’. No public news of this and no useful updates from @British_Airways — anyone out there know any more?”
Another said: “With respect, it is impacting journeys departing B gates – BA710 to Zurich delayed by +2 hrs and aircraft change required. Sending good wishes to injured staff.”
And another wrote: “Well that’s disingenuous when 200 people in this plane are stuck. Tosh.”
One passenger who had been on a Zurich-bound flight, told The Sun: “We boarded and waited and then the captain gave a series of apologies and further delay announcements.
“It looks like some airport or airline staff may have been injured and police required an area to be closed off which prevented some planes from leaving their gates.”
“The gate was surrounded by various airport service vehicles including two fire engines. There were blue lights everywhere.”
British Airways confirmed: “A number of stands at Terminal 5 are currently inaccessible and this is causing some delays.
“We are sorry for any inconvenience caused.”
