President François Hollande on Saturday called the attacks that killed more than 120 people in Paris an "act of war," and said that ISIS was to blame.
Hollande declared three days of mourning following the series of seemingly coordinated terror attacks in the French capital on Friday night. At one point, more than 100 people were taken hostage at a concert hall, leading to a police raid on the venue.
ISIS claimed responsibility for the attacks, releasing statements in French and Arabic.
In a statement posted on social media, ISIS claimed France would “remain on the top of the list of targets”.
“This attack is the first of the storm and a warning to those who wish to learn,” the statement said.
Officials released a provisional death on Saturday morning of 127 killed with 99 people in critical condition. At least eight of the attackers died, some by detonating suicide bombs, police said. It's unclear if all of the suspected assailants are dead. No information has been released about their motive.
Four of the attackers died at the Bataclan theater, three at the Stade de France, and one on the Boulevard Voltaire. All but one of the attackers at the Bataclan died after detonating explosives on their person. None of them have been identified.
President François Hollande called the terror attack unprecedented — declaring a state of emergency, and ordering extraordinary security measures. French police told people to not leave shelter for several hours. Hollande ordered everyone at the nation's borders to be checked, and empowered authorities to forbid the movement of people. 1,500 military members were moved into the city.
"It's horrifying," Hollande said in an address to the nation. "This is a terrible ordeal which once again assails us."
The assailants waged their attack on six fronts: the popular Bataclan concert hall, a bar and restaurant on Rue Alibert, a restaurant on Rue de Charonne, the national soccer stadium, and a shopping center.
President Obama said, “This is not just an attack on Paris, not just on the people of France, but this is an attack on all of humanity."
A state of emergency hadn’t been declared in France since the riots of 2005. City officials announced that all public buildings closed would be closed on Saturday in Paris, including schools, museums, libraries, sporting halls, pools, and markets.
Taxi drivers are driving people away from the scenes for free and people were offering strangers shelter.
There were multiple fronts throughout the city:
* At the Bataclan concert hall, gunmen entered though the front door armed with semi-automatic weapons and began firing into the crowd, witnesses said. Dozens were killed and some 100 people were taken hostage.
The Eagles of Death Metal, an American rock band, play at the venue Friday night. The concert hall is located in the 11th arrondissement, a trendy central district.
"Several armed men came into the concert," Julien Pierce, a reporter for Europe 1 who was at the Bataclan during the attack, told the BBC. "Two or three men, not wearing masks, came in with what looked like Kalashnikovs and fired blindly on the crowd. It lasted between 10 and 15 minutes. It was extremely violent and there was panic. The attackers had enough time to reload at least three times. They were very young."
“They said nothing," Pearce said, describing it as a "bloodbath."
"They just shot."
"They shot right into the crowd, shouting Allahu Akba [God is great]" one person who escaped the Bataclan told AFP. Another person who fled the concert venue told AFP they heard someone say, "This is for Syria." Those alleged statements have not been confirmed by officials.
Police raided the theater, and several of the assailants detonated suicide explosives.
None of the band members were injured in the attack. Read more about that incident here.
* At the Le Petit Cambodge restaurant and Le Carillon bar on Rue Alibert, witnesses said on social media that the gunmen used assault rifles to open fire on the crowds. The restaurant is located in the 10th arrondissement, a trendy district that is also home to a large and diverse immigrant community.
* At Le Belle Equipe restaurant, on Rue de Charonne, witnesses on the scene said on social media that at least six people had died, but there were no official estimates of the number of fatalities. It's located in the 11th arrondissement.
* At the Stade de France, on Boulevard Voltaire, several died in an explosion outside the stadium. The French national team was playing a friendly match against Germany. President Hollande, who was watching the game, left the stadium to attend an emergency meeting, according to the French Ministry of the Interior. The stadium is located in Saint Denis, a suburb just north of the Paris city limits.
* Another shooting was also reported at Les Halles, a mall in central Paris on Rue de la Fontaine-au-Roi, Reuters reported, citing local media. The GIGN, a heavily armed elite police unit, deployed to the market, Le Monde reported. There were no immediate reports on the number of casualties. It's in the 1st arrondissement, at the heart of Paris.
In a statement, the Élysée Palace, the president’s office, said Hollande's state of emergency decree also empowered authorities to forbid the movement of people. Authorities also had the power to place people under house arrest if their activity was deemed dangerous, temporarily close theaters and meeting places, force people to surrender weapons, and carry out searches, the Élysée Palace said.
Paris police later wrote on Twitter that all public street protests were suspended until further notice.
The French president had mobilized an additional 1,500 soldiers, the palace said, and called a meeting of his defense council for Saturday morning.
The president’s office added that Hollande would not be attending the upcoming G20 conference in Turkey, and he would instead be represented by his foreign affairs and finance ministers.
The attacks come just months after 12 people were killed at the magazine Charlie Hebdo by two brothers angry about its depictions of the Prophet Muhammad.
"It's a heavy recollection of what happened in January," Deputy Paris Mayor Patrick Klugman told NBC, referring to the massacre at Charlie Hebdo in Paris. "Now we are struck again. This is harder. I am shaken"
Social media users who said they witnessed the attack said assault rifles were used in the shooting. U.S. officials believe the attacks were coordinated, Reuters reported.
Remy Buisine, a witness at of the shootings, live-streamed the scene via Periscope from Place de la République, a large public square nearby the Bataclan concert hall.
In the live stream, Buisine recorded heavy police presence, and one seeming altercation between police and a number of figures.
In the midst of the recording, police told Buisine to get on the ground. Buisine said he heard multiple gunshots before the video began cutting out. A number of people hiding behind police cars could be seen throughout the recording.
An official fatality count has not been released.
One person on Facebook claimed he was inside the concert hall:
"I am still at the Bataclan. First floor. Seriously wounded. They're giving attack quickly. There are survivors inside. They cut down everyone. One by one. 1st floor soon!" he wrote.
"Alive. Just cuts... Carnage... Dead bodies everywhere.."
French Senator Nathalie Goulet told France 24 TV that the terrorist attacks were a “nightmare…there’s no other word.”
She also said that without a massive surge in cross-border cooperation in terms of intelligence sharing and other resources, “it’s not possible” to insulate France from the sort of terrorist attack seen Friday night.
Goulet said intelligence officials were “aware” that a terrorist attack would happen at some point, that the assailants rely on the element of surprise, making it nearly impossible to intervene every time.
“Those people just act to kill,” she said.
At the stadium, a loud blast could be heard during game play:
People were allowed onto the field after game play was stopped:
Hélicoptère, pelouse envahie, scènes surréalistes.
Gunshots can be heard in this Instagram post from a witness:

The hashtag Pray For Paris has swept over social media:
