As France initiates a state of emergency and begins several days of mourning, here is a breakdown of what we know so far:
Six separate attacks were carried out across Paris, beginning after 10 p.m. local time Friday night.
One of the targets was the Stade de France soccer stadium, where Germany was playing France in a game that French President Francois Hollande was attending. Hollande was evacuated from the stadium.
At least 80 were killed inside the Bataclan concert hall, where American rock band Eagles of Death Metal was playing. A witness in the theater told ABC News she heard gunmen shout "Syria!"
The four other attacks were at other locations in the 10th and 11th districts of Paris, where gunmen targeted bars and restaurants. Police said some attackers first sprayed cafes outside the venue with machine gunfire before continuing the assault inside the concert hall.
At least 129 people were killed and 352 were injured, Paris prosecutor François Molins said.
Of the injured, 99 were in critical condition, said Molins.
An American college student studying abroad in Paris was among those killed.
Hollande blamed terror group ISIS for the attacks, which he called “an act of war.”
Molins said today seven "terrorists were killed during their criminal actions." Earlier, ISIS had claimed eight "brothers" took part in the operation, the same number of attackers seen in early local media reports.
Molins said three teams of attackers coordinated the attacks. He said the attackers in the Bataclan concert hall mentioned Syria and Iraq during the attacks. One suspect was identified as a 30-year-old French citizen.
All suicide attackers wore identical explosives vests, said Molins.
One suicide attacker, identified by a Syrian passport found near his body at the national stadium, was not known to French intelligence services, Molins said.
Belgium's federal prosecutor's office said authorities have made three arrests linked to the attacks.
ISIS today released a statement claiming responsibility for the attack. In an audio statement released online in Arabic and French, the group said ISIS "soldiers" targeted the "capital of prostitution and obscenity." The statement claimed the attack was the "first of the storm and a warning to those who wish to learn."
A State of Emergency in France
France is in a state of emergency as an additional 1,500 soldiers have been mobilized to guard Paris's parliament buildings, religious sites and tourist attractions.
All public buildings in Paris, including schools, museums, libraries and town halls, were closed indefinitely starting Saturday.
Police said public demonstrations would be banned in the Paris area until Thursday.
Hollande has declared three days of national mourning.
The French flag was at half-mast on top of the Elysee palace, the official residence of Hollande.
The management of the Eiffel Tower has decided to close the attraction indefinitely, AFP reported, and the Mayor of Paris, Anne Hidalgo, said the tower’s lights will be switched off tonight.
