Minutes before he slung an assault rifle across his chest and walked through a high-speed train, the Moroccan suspect in the foiled attack watched a jihadi video on his cellphone, the French prosecutor said in formally opening a terrorism investigation Tuesday.
The actions by Ayoub El-Khazzani on the Amsterdam-to-Paris train Friday night and information from other European authorities on his travels and apparent links to radical Islam prompted the investigation, said prosecutor Francois Molins.
El-Khazzani, 26, was tackled and tied up by five passengers, including three Americans and a Briton, averting what President Francois Hollande said "could have degenerated into monstrous carnage."
