KEY POINTS:
Two planes have collided while taxiing on a runway at London's Heathrow Airport, according to the UK's Sky News.
Up to 20 fire appliances at the scene have since left.
A witness earlier told Sky News that nobody appeared to be hurt, but one of the planes had lost an engine.
This report was later denied by the Fire Service, which said the planes had just clipped each other, and that there were no injuries.
"It was a minor collision in between two planes who just clipped each other," a fire brigade spokesman told Associated Press.
"There was no fire, no injuries, no damage."
BBC is reporting that the planes were a British Airways Boeing 747 and a Sri Lankan Airlines Airbus A340.
