A plane has crashed in the northern US state of Montana, aviation officials say, with reports of some fatalities.
US news reports said a small plane crashed as it approached the airport in the town of Butte.
A Federal Aviation Administration (FAA) spokesman told the AP news agency that 17 people had been killed, with some children among the dead.
The small single-engine plane crashed some 500ft (150m) from Butte's airport while attempting to land, he said.
An FAA spokesman told the BBC that the plane crashed at approximately 1527 local time (2127 GMT).
Les Dorr said the plane was a Pilatis PC-12 Swiss-made turboprop aircraft.
Preliminary information says it was en route from Orville, California to Butte, he said. The spokesman stressed that the numbers of those killed can be very fluid early on in a crash, and that nothing could be confirmed at this stage.
