Train crash eyewitness: 'I could see people crying'

Friday's train crash south of Paris was "like watching a movie," according to one eyewitness in France.

Karim Wone was seated on another train at Bretigny-sur-Orge station when a train, heading for Limoges, derailed at high speed.

The crash, which left six people dead, may have been caused by a fault in the rail tracks, the state rail company has said.
