Stories of incredible courage are beginning to emerge from the horror in Nice.
As the killer barreled along the promenade Thursday night, one man reportedly jumped on the 18-ton truck in an effort to stop him.
The unidentified hero threw himself at the vehicle as it zig-zagged along the promenade, an attack that resulted in the death of 84 people and left 200 others injured.
"A person jumped onto the truck to try to stop it," witness and local lawmaker Eric Ciotti told Europe 1 radio. "It's at that moment that the police were able to neutralize this terrorist."
Ciotti said the driver, Tunisian-born Frenchman Mohamed Lagouaiej-Bouhlel, tried to shoot the person but missed. Police, including a female officer, then swooped in.
"I won't forget the look of this policewoman who intercepted the killer," Ciotti added.
Other attempts were made by brave civilians to bring an end to the carnage.
A motorcyclist sped alongside the truck before attempting to get inside the cabin, a German journalist told Agence France-Presse, but the biker fell and was pulled under the wheels instead. Footage taken from nearby buildings appears to confirm the account. The man's condition is unknown.
The killer, a delivery man and divorced father of three who lived in Nice, was shot dead by police.
