Two men have died in a light aircraft crash at a race track.
Emergency services were first called to Darley Moor race track at about 11:30 BST on Tuesday and remain at the scene, Derbyshire Police said.
People have been urged to avoid the area, which is just over three miles from the town of Ashbourne in Derbyshire.
The Air Accidents Investigation Branch (AAIB) has launched an investigation into the crash and flying restrictions are in place.
The order, signed by the transport secretary, states that no aircraft must fly below 1,600ft (488km) above mean sea level over the Darley Moor area.
