Three people, were injured Friday when at least one gunman armed with an AK-47 and knife opened fire on a train headed from Amsterdam to Paris.
The gunman was overpowered by two off-duty U.S. Marines, who heard the suspect load his gun and tackled him, The Telegraph reported.
The train stopped in the French town of Arras, where police arrested the gunman, who is said to be of “North African origin.” Police are evacuating the train station.
A third person, French actor Jean-Hugues Anglade, was also wounded.
Counterterrorism police have taken over the investigation, but authorities have not said whether the attack was an act of terrorism.
