The three friends from the United States traveled in Europe as vacationers. Now the world knows them as heroes.

Anthony Sadler, Spencer Stone and Alek Skarlatos were aboard a high-speed train en route to Paris from Amsterdam on Friday when a gunman opened fire.

Along with two others — a French national and a Briton — they charged, tackled and subdued him, officials said.

The gunman was Ayoub El Khazzani, a Moroccan national, a senior European official told CNN.

U.S. President Barack Obama called the three Americans heroes. He spoke to them by phone Saturday, commending and congratulating them for their courage and quick action.

His French counterpart, Francois Hollande, saluted the Americans’ bravery and planned to host a meeting with them Monday that will include top government ministers. He will present them with Legion of Honor medals, France’s highest recognition, according to the President’s website.
