The man whose attack on a high-speed train in France was thwarted by passengers was carrying 270 bullets for his assault rifle and a bottle of petrol, a French prosecutor said Tuesday.

Ayoub El Khazzani, 25, was also carrying a  Luger pistol and a box-cutter, and had watched a jihadist video on YouTube on his mobile phone before carrying out the attack, prosecutor Francois Molins said.
