A high-speed TGV train has derailed near the eastern French city of Strasbourg, killing at least 10 people, BBC News reported.
The crash happened during a test run in the town of Eckwersheim, on a new Paris-Strasbourg line.
The train was carrying 49 railway technicians when it derailed, caught fire, and plunged into a canal. Eleven people suffered serious injuries.
The derailment was due to "excessive speed", officials say.
