A coordinated terrorist attack in and around the city of Paris, France, on Friday night has reportedly left at least 100 dead.
According to CNN, one of the venues targeted was the Bataclan concert hall. On Friday, the Eagles of Death Metal, an American rock band formed by Jesse Hughes and Queens of the Stone Age's Josh Homme, and French band Red Lemons were performing a sold-out concert at the venue. According to ConsequenceofSound.net, police believe terrorists are holding 100 hostages inside the venue.

Eagles of Death Metal and Red Lemons are not hostages and are OK, according to a post on the Red Lemons' Facebook page.
"A terrorist attack happened at the Eagles of Death Metal concert. We are safe," the message read. "Mikel Ross, Eric McFadden, we were with your mates Jesse, Tuesday [Cross], the other musicians outside, they're safe too, they took a cab."
Homme did not travel to Paris for the European tour.
Jared Followill of the Kings Of Leon also tweeted about the musicians' safety.
Later, Eagles of Death Metal updated their Facebook page, writing that they were still unclear about the whereabouts of all of their members.
"We are still currently trying to determine the safety and whereabouts of all our band and crew," the post read. "Our thoughts are with all of the people involved in this tragic situation."
One of the drummers for Eagles of Death Metal is Atlanta native Julian Dorio. His brother Michael spoke to Atlanta's Channel 2 Action News, saying that his brother is OK and the police station in Paris.
"He said they were playing, about six songs into the show, they heard, before they saw anything, they heard automatic machine gunfire," Michael said. "It was so loud, it was louder than the band, and they hit the stage floor. As they got up to try to evacuate they saw men with machine guns just shooting anything and everything in the venue. Fifteen hundred people, Julian said, was about the capacity of the venue. I don't know if it was seated or standing but Julian, the lead singer and some of the crew, there was a door back of the stage that led to a street and they flew out the back door."
CNN reports that multiple gunmen entered the venue and used AK-47 automatic weapons to open fire on law enforcement. According to the news source, police had taken a rooftop position to fire back from.
According to CNN, French President Francois Hollande, Prime Minister Manuel Valls and Interior Minister Bernard Cazeneuve are holding a crisis meeting to address the attacks.
CNN reports that at least six shootings took place in Paris and explosions were heard at the Stade de France during a soccer match between France and Germany. Geraldo Rivera revealed that his 21-year-old daughter Simone was at the stadium during the attacks, but reportedly escaped.
President Barack Obama spoke out about the attacks on Friday, saying, "This is an attack not just on Paris. It's an attack not just on the people of France. But this is an attack on all of humanity and the universal values we share."
The president also assured that the United States is "prepared and ready" to provide assistance.
U2 has concerts scheduled at AccorHotels Arena in Paris for Saturday and Sunday, with Saturday's performance slated to air live on HBO. ET has reached out to HBO and a source close to production said it's unlikely the show will go on, but there has been no official decision as of yet.
AOL confirms to ET that Al Gore was at the Eiffel Tower for his annual 24-hour live webcast/telethon about climate change when the attacks began but that they canceled the livestream when President Hollande asked them to shut down the broadcast.
Many stars have sent their thoughts to those affected by the attacks via social media.
