ARRAS, France: A heavily-armed man opened fire in a "terrorist attack" on a high-speed train travelling from Amsterdam to Paris on Friday (Aug 21), injuring at least two people before being overpowered by two American passengers.
The motives for the shooting were not immediately known, although French prosecutors said a probe was being launched by counter-terrorism investigators.
The suspect, who was arrested at a railway station in northern France, was identified as a 26-year-old from Morocco or of Moroccan origin who was known to the intelligence services, French investigators said.
France has been on edge since Islamist gunmen went on the rampage in January, killing 17 people in the capital Paris.
"I condemn the terrorist attack on the Thalys (train) and express my sympathy to the victims," Belgian Prime Minister Charles Michel said on Twitter of the incident which occurred while the train was on Belgian territory.
