PARIS (AP) — French authorities say a train carrying nuclear waste has derailed in a Paris suburb, but no leaks, injuries or other problems have been reported.

An official with the national fire service says experts carried out radiological tests after the incident Monday in Drancy, and found no leaks.

The official said the train was traveling slowly and went about 50 centimeters (20 inches) off the rails, and an investigation will be carried out. The official was not authorized to be publicly named according to fire service policy.

Jean-Michel Genestier, deputy director of rail company SNCF Geodis, said on BFM television that it was "a minor incident."

Drancy Mayor Jean-Christophe Lagarde expressed concern about the safety of the nuclear and chemical trains that pass regularly through his town.
