A French fighter jet carrying two pilots has disappeared from radar screens near the Swiss border, prompting fears it may have crashed.
A French air force spokeswoman said the Mirage 2000D was last detected in a snow-covered mountainous area between the Doubs and Jura regions.
She said a search is under way for signs of the plane and its pilots, believed to be a man and a woman.
The jet took off shortly after 11am local time from the Nancy-Ochey air base in north-east France.
Regional newspaper L'Est Republicain reported that debris, a parachute and a map had been found in the search.
According to the paper one local resident "heard the plane around 10:15 am. This is a busy corridor and they often go very low, but suddenly I heard a thud and then nothing."
