Over 100 people have been killed in seven coordinated attacks in Paris on Friday night, the Associated Press reports.

Gunmen opened fire at a café near Rue Charonne, while three explosions struck at the Stade de France stadium during a match between the French and German national soccer teams.

Several hundred people had been held hostage by gunmen at the Bataclan theater, where a sold-out concert for California rock duo Eagles of Death Metal was taking place. French security forces launched an assault on the theater and have killed at least two attackers. The number of victims is expected to rise, as one official described the scene inside the theater where attackers had tossed explosives at the hostages.

A French police official says at least 100 people were killed inside the concert hall.

A fourth attack was also reported at Les Halles, which is a shopping center in Paris, Reuters reports.

French President Francois Hollande has declared a state of national emergency. "This is a terrible test, another assault on France," he said. "We must, in these difficult moments, prove our compassion and unity." The attacks come less than a year after the Charlie Hebdo tragedy.

It is not yet clear who is responsible for the attacks and suspects have not yet been identified, though witnesses in the theater say that shooters were screaming, "This is for Syria," before gunning down patrons.

"Once again we've seen an outrageous attempt to terrorize innocent civilians. This is an attack not just on Paris, it is an attack not just on the people of France, but this is an attack on all of humanity and the universal values we share," said President Obama, according to the New York Times.
