A French fighter jet carrying two pilots has disappeared from radar screens near the Swiss border.
A French air force spokeswoman said the Mirage 2000D was last detected Wednesday in a snow-covered mountainous area between the Doubs and Jura regions. She said a search is underway for signs of the plane.
The spokeswoman wasn't authorized to be publicly named.
The plane took off soon after 11 am (1000 GMT; 5 am EST) from the Nancy-Ochey air base in northeast France.
