At least 35 people have been killed in Paris after multiple explosions and shootings at at least four different locations throughout the French capital, authorities said.
Hostages have also been taken at the Bataclan concert hall, police said, where a sold-out rock concert was underway.
Approximately 100 people were inside the hall, watching an Eagles of Death Metal show, authorities said.
"We are all terrified, and have been told to get away as soon as possible," said Gilles Avel, a 19-year-old student who was enjoying a night out with friends close to the Bataclan. "There were shots and then lots of people running. We knew there was a rock concert going on in the Bataclan."
Anti-terrorist police could be seen flooding into the area, as well as soldiers.
Two people opened fire at the Le Carillon bar, while another shot up the Cambodge restaurant in the city’s 10th district, according to French media cited by the BBC.
Kalashnikov-wielding gunmen attacked a Korean restaurant in the Bastille area of the city, while grenade blasts were also heard.
It is thought that at least 11 died in the restaurant shootout, while gunfire was also heard in other bars around the French capital.
The shootings happened along Rue de la Fontaine au roi, Rue de Charonne and Rue Bataclan, Le Figaro reported.
Two explosions were heard at a bar near Stade de France, where France was hosting Germany in a soccer game. President Francois Hollande was there and was taken out by security, Le Figaro reports.
The explosion was loud enough to hear inside the stadium, over the roaring of 75,000 fans, according to an Associated Press reporter at the match.
At least one of the explosions was reportedly carried out by a suicide bomber.
A BBC journalist reported seeing 10 bodies of either dead or wounded lying in the street.
The French deputy prime minister has yet to call the attacks terrorism. He did say three people had died in the explosion near the stadium.
President Obama has been briefed by his counter terrorism adviser. The Department of Homeland Security said there are no specific threats
"I am shocked by events in Paris tonight," British Prime Minister David Cameron said in a statement. Our thoughts and prayers are with the French people. We will do whatever we can to help."
There's been no claim of responsibility, but the attacks come just a day after the United States announced a drone strike in Syria that likely killed Jihadi John, the Islamic State's British-accented executioner.
NYPD officials have been in touch with authorities in France, said Stephen Davis, the NYPD’s top spokesman.
“We’re monitoring it closely,” Davis said.

The NYPD has an officer stationed in Paris.
The attacks were carried out not far from the headquarters of the Charlie Hebdo newspaper, where 12 people were shot dead in January in an attack carried out by radicalized Islamic extremist brothers.
Four Jewish shoppers were also murdered in the same set of attacks inside a Kosher supermarket in nearby Vincennes.

The French capital has been on a high state of alert ever since, with security services warning that another attack was always likely.
In August, a trio of Americans were able to tackle and detain a gunman before he carried out an attack on a train headed for Paris from Amsterdam.
