At least one person has died after two planes collided in mid-air at an airshow in northern Switzerland.

Police said the two aircraft were in a formation of three planes when they crashed in Dittingen on Sunday morning.

There were no further details on casualties.

Daniel Fierchter, a spokesman for the Dittingen airshow, said rescue teams had just arrived at the scene.

It came a day after seven people were killed when a vintage plane crashed at the Shoreham Airshow in the UK.

The Hawker Hunter jet nosedived onto the A27 at Shoreham, West Sussex, smashing into cars after it failed to pull out of a loop-the-loop stunt.

Seven people are known to have died, but police warned more bodies may be found.

Horrified onlookers described seeing the plane flying low to the ground followed by a "huge ball of fire and black smoke".

The crash has raised debate about the safety of airshows, particularly near busy roads.
