At least 127 people have been reported dead in attacks at six locations around Paris Friday, the country's most violent day since World War II.
The entire city is in a "state of emergency" and the public is encouraged to stay indoors all day. Parks, museums and all other public facilities are closed.
The last state of emergency in France was in 2005.
ISIS has claimed responsibility for what French President Francois Hollande called "an act of war."
The BBC cited French sources that said more than 200 people were injured, including 80 who were critically injured.
At least 118 people were killed at a theater where hostages were held after an initial attack, according to the city's deputy mayor. The siege ended when French police stormed the concert hall, killing the attackers, at least three of whom were wearing explosive belts.
The Paris prosecutor said in an update early Saturday in Paris that eight attackers were dead following the assaults, including seven who died in suicide bombings.
The head of the Paris police said all attackers were believed to be dead. But some reports questioned whether all the attackers were accounted for.
Reporters at the scene said French police launched the assault on the concert hall theater at around 6:45 p.m. (ET).
The people at the theater were attending a concert by The Eagles of Death Metal, a rock band from Palm Desert, Calif.
An Atlanta drummer was onstage with the band when the gunmen entered the theater, according to the Atlanta Journal-Constitution. He and other band members were able to escape.
#PorteOuverte hashtag
Those seeking safety from the attacks in Paris were using the hashtag #PorteOuverte. It means "open door" and was started to offer safe shelter to people in the city.
President François Hollande makes a statement
5:50 p.m. (ET) - The French President, who was evacuated from the stadium when the explosions hit, declared a state of emergency, imposing travel restrictions within the country and shutting down the borders.
President Obama makes a statement
5:40 p.m. (ET) - President Obama spoke from the White House Friday, calling France the oldest ally of the United States and saying the attacks in Paris were an "outrageous attempt to terrorize innocent civilians."
Obama said he had not yet spoken with the French president about the attacks but said he expected to be coordinating with the French over the next few days.
Obama said he did not want to speculate about who was responsible until more information was in hand.
Bataclan theater
The siege ended when Paris police stormed the concert hall, killing at least two attackers.
A band member had tweeted a photo of the venue Friday afternoon, before the concert and before the attack.
Paris restaurant
A police official said 11 people were killed in a Paris restaurant in the 10th arrondissement.
Emilioi Macchio, from Ravenna, Italy, was at the Carillon bar near the restaurant that was targeted, having a beer on the sidewalk when the shooting started. He said he didn't see any gunmen or victims, but hid behind a corner then ran away.
"It sounded like fireworks," he said.
Stade de France stadium
Also late Friday, two explosions were heard outside the Stade de France stadium north of Paris during a France-Germany friendly football match. It is unclear if the explosions were linked to the other events.

A police official confirmed one explosion in a bar near the stadium.
An Associated Press reporter in the stadium Friday night heard two explosions loud enough to penetrate the sounds of cheering fans. Sirens were immediately heard, and a helicopter was circling overhead.
The officials spoke on condition of anonymity because they were not authorized to be publicly named.
Heightened security due to global climate conference
The attack comes as France has heightened security measures ahead of a major global climate conference that starts in two weeks, out of fear of violent protests and potential terrorist attacks.
France has been on edge since deadly attacks by Islamic extremists in January on satirical newspaper Charlie Hebdo and a kosher grocery that left 20 dead, including the three attackers.
The restaurant targeted Friday, Le Carillon, is in the same general neighborhood as the Charlie Hebdo offices.
The country has seen several smaller-scale attacks or attempts since, including an incident on a high-speed train in August in which American travelers thwarted a heavily armed Islamic radical trying to attack passengers.
