The assault was described as a terrorist attack. President Barack Obama has expressed his gratitude for the "courage and quick thinking" of the passengers on a high-speed train in France, including U.S. service members, who overpowered the gunman. Bernard Cazeneuve, the French interior minister, paid tribute to the Marines as he arrived at the scene, and said "Thanks to them we have averted a drama. The Americans were particularly courageous and showed extreme bravery in extremely difficult circumstances."
