Rescue workers searched for survivors early Saturday, hours after a high-speed train derailed just south of Paris, killing at least six people and injuring 30 more.

The accident, in which the train crashed into a station platform on Friday afternoon, is France's worst rail disaster in 25 years.

Rescue teams, working under arc-lights, spent the night checking the wreckage of overturned carriages to see if any passengers were still trapped inside and if there were any more bodies to be recovered.

Witnesses said the site of the crash resembled "a war zone". One survivor described walking over a decapitated body to escape an overturned carriage.

The train was a regional service heading from Paris to the west-central city of Limoges. It derailed as it passed through the station at Bretigny-sur-Orge, about 25 kilometers south of Paris.

Prime Minister Jean-Marc Ayrault, speaking from the accident site late on Friday, told reporters: "The toll is currently six dead, 30 injured, of whom eight are in a serious condition."

Four carriages of the train were derailed in the incident -- and three of those overturned.
