Two airliners have been involved in a collision while taxiing at Heathrow Airport in West London.

One was a British Airways Boeing 747 departing for Singapore and the other was a SriLankan Airlines Airbus A340.

Heathrow's operator, BAA, confirmed there had been an incident at around 2220 BST and there had been no reports of injuries, said a BBC report.

BA said there had been a 'minor collision' involving flight BA011 and passengers were back in the terminal.

A BAA spokesman said: 'Heathrow airport can confirm that two aircraft were involved in an incident earlier this evening on the ground.

'There are no reported injuries.'

A spokesman for British Airways said an investigation had been launched.

The spokesman said: 'Engineers are inspecting the aircraft to ascertain the damage.

'We do not have any more precise details of the collision while it is being investigated.'

He added that passengers had been offloaded safely and were now in the terminal building.

They would either be given the option of a refund or spend the night in a hotel before leaving on the next available flight.

The London Fire Brigade said it was alerted at 2213, although its crews had been stood down by 2228.

A spokesman for the London Ambulance service said: 'We were called to the airport at about 2220 BST, but we were stood down around 10 minutes later as there were no injuries.'
