A British consultant and three young Americans have been praised by David Cameron for their bravery after they overpowered a gunman on a train in France.
Chris Norman, 62, was travelling from Amsterdam to Paris aboard the high-speed Thalys train when the heavily armed man opened fire.
He helped US Air Force serviceman Spencer Stone, National Guardsman Alek Skarlatos and Sacramento State University student Anthony Sadler to get the man under control.
Downing Street said the Prime Minister had praised them for their bravery.
A No 10 spokesman said: "The Prime Minister praised the extraordinary courage of the passengers who intervened and helped disarm the gunman, including the British consultant Chris Norman.
"The bravery of Mr Norman and the other passengers helped to prevent a terrible incident."
