UPDATE: 2:30 p.m. EDT — A terror attack in Nice that saw dozens killed and more than 200 injured could hurt French President Francois Hollande's plans to seek a second five-year term next year, the New York Times reported. His critics slammed him Friday for not doing more to protect France. 

Alain Juppé, a former prime minister, told RTL radioFriday morning that "if all the means had been taken, this tragedy would not have occurred." He called for improved intelligence sharing.

UPDATE: 2:14 p.m. EDT — Newt Gingrich blamed reporters Friday for "hysteria" over his comments that the United States should "test" U.S. Muslims about their loyalty to Shariah law.

"The hysteria of the media overreaction to my comments on the Nice attack is very revealing," he wrote on Twitter.

Gingrich called for the U.S. to "monitor the mosques" during a Fox News interview Thursday night soon after a man drove into a crowd celebrating Bastille Day in France and killed dozens of people. 

"Western civilization is in a war. We should frankly test every person here who is of a Muslim background and if they believe in Shariah they should be deported," Gingrich said during the interview. "Shariah is incompatible with Western civilization."

The White House slammed Gingrich Friday over the remarks. "Observations like that, or proposals like that or rhetoric like that are un-American," White House press secretary Josh Earnest said. "Our nation was founded on the principle that people can choose to worship as they please without harassment from the government."

UPDATE: 9:50 a.m. EDT — French President Francois Hollande said Friday a police officer and about 83 other victims were likely among those killed during a Bastille Day celebration in Nice. The death toll continued to grow as officials investigated the motive of the attack.

Even people who have no signs of physical injury, will carry throughout their lives the trauma of the horrific images they saw," Hollande said. "I have tears in my spirit about this young policeman who acted so that killer should be neutralised, and put an end to the carnage. The security services have answered all the demands and the calls upon them."

Hollande said officials were investigating whether the attacker acted alone. 

"There are 50 other people who are still receiving emergency treatment. They are between life and death. Among the victims are French citizens as well as foreigners, who came from all continents.

Original story:

More than 100 were injured and at least 30 were killed after a driver rammed his truck into a crowd of people in Nice, France, in a suspected terror attack. French President Francois Hollande headed to his crisis center after the attack that unfolded as fireworks erupted in the sky on Bastille Day, a national day of celebration.

As many as 60 people were reported dead in conflicting media reports as the details began to be made public. The driver was shot soon after the attack. It was not immediately known whether he acted alone. Witnesses reported gunshots and posted images of dead bodies, the New York Times reported. 

"People were running - it's panic," a journalist from Nice told Le Monde. "The scene is awash in blood of the wounded."

The attack came after France lost dozens of citizens in a mass terror attack in Paris in November. That attack was carried out by Belgium nationals who had pledged support for the Islamic State group. Other mass killings have unfolded in the United States, Brussels, Iraq and other nations battling supporters from the militant network also known as ISIS. 

The mayor of Nice, Christian Estrosi, tweeted out Thursday soon after the attack: "Dear Nice, the driver of a truck seems to have left dozens dead."

The sub-prefect of the Alpes-Maritimes department, Sébastien Humbert, told the French network BFMTV: "There are several dozen dead. The total is very high, thirty dead. Maybe 100 wounded. There was a truck that drove into the crowd, over a very long distance. There were shots. The driver was shot. This is on a big scale."

In the United States, Republican presidential candidate Donald Trump, who has promised to improve national security by banning Muslims, quickly linked the crash to terror. "Another horrific attack, this time in Nice, France. Many dead and injured. When will we learn? It is only getting worse," he tweeted.
