The death toll following yesterday's high-speed train crash in France has risen to 11.

A spokesperson for French rail company  SNCF said children are among the 37 injured, 12 of whom remain in critical condition.

The TGV train derailed near the eastern French city of Strasbourg during a test run in the town of Eckwersheim, on a new Paris-Strasbourg line.

The train was carrying 49 people when it derailed, caught fire, and plunged into a canal. 

SNCF has said that several unauthorised people were on board the test train and that a probe will investigate this.
