At least 84 people were killed Thursday night in France when a truck plowed through a Bastille Day celebration in the city of Nice. Fifty people are "between life and death," French President François Hollande said. He called the tragedy a terror attack.

"There are 50 other people who are still receiving emergency treatment," he said, according to the Guardian. "Amongst the victims are French citizens as well as foreigners, who came from all continents. And there are a number of young children who came to watch fireworks with their families, who have been struck down just to satisfy the cruelty of one individual or possible of a group."

Graphic photos of the attack quickly emerged. Bullet holes in the windshield of the truck show law enforcements attempt to stop the attacker, who was identified as 31-year-old Mohamed Lahouaiej Bouhlel. He was a resident of Nice.

Hollande was adamant about the assault being a terror attack. "France has been hit on the day of celebration. This is a form of sabotage. Human rights are not respected by these fanatics," he said, according to Al Jazeera. "We will further strengthen our actions in Iraq and in Syria. We will continue striking those who attack us on our own soil."

U.S. President Barack Obama condemned what appeared to be "a horrific terrorist attack," according a statement the White House released.

"I have directed my team to be in touch with French officials, and we have offered any assistance that they may need to investigate this attack and bring those responsible to justice," he said. "We stand in solidarity and partnership with France, our oldest ally, as they respond to and recover from this attack."
