PARIS — Paris prosecutor Francois Molins says 129 people were killed in the Paris terror attacks and 352 people were injured.
He says 99 of the injured are in critical condition.
Molins says three teams of attackers seem to have coordinated the attacks.
He added the attackers in the Bataclan concert hall, where 89 people died, metioned Syria and Iraq during the attacks.
The Islamic State group claimed responsibility for the gun and bomb rampage that also targeted restaurants and a soccer stadium.
ISIS claimed responsibility for the Friday attacks in an online statement early Saturday morning.
The claim was made in Arabic and French, and was circulated by supporters of the group.
It was not immediately possible to confirm the authenticity of the statement, but it bore the group's logo and resembled previous statements issued by the group.
French President Francois Hollande, who was at the soccer stadium when it was attacked, addressed the nation Saturday after an emergency security meeting.
He declared three days of national mourning, and put the nation's security at its highest level.
Hollande says ISIS committed "an act of war."
He said France "will be merciless toward the barbarians of Islamic State group" and will "act by all means anywhere, inside or outside the country."
The Paris prosecutor's office says that eight attackers are dead, seven of them in suicide bombings.
A spokeswoman says the eighth attacker was killed by security forces when they raided a concert hall where the assailants had taken hostages. She said it's possible that there are terrorists still at large.
Two French police officials who spoke on condition of anonymity, say a Syrian passport was found on the body of one of the suicide bombers who targeted France's national soccer stadium.
Belgium said Saturday it has made more than one arrest in connection with the attacks.
From the Vatican to Persian Gulf states, the reaction to the Paris terrorist attacks is universally one of condemnation and expressions of solidarity with France.
President Barack Obama is calling the attacks an "outrageous attempt to terrorize innocent civilians."
Secretary of State John Kerry is describing the attacks as "heinous, evil" and "vile."
U.N. Secretary-General Ban Ki-moon called the attackers "despicable."
And German Chancellor Angela Merkel says the attacks left her deeply shaken.
British Prime Minister David Cameron tweeted, "Our thoughts and prayers are with the French people. We will do whatever we can to help."
Canadian Prime Minister Justin Trudeau says Canada has offered "all of our help and support to the government of France." He says "Our hearts and thoughts and prayers go out to our French cousins in this dark and terrible time."
Iranian President Hassan Rouhani condemned the attacks and said the fight against terrorism must go on.
Persian Gulf countries also condemned the attacks.
And Foreign Ministry spokesman Hong Lei says China is "deeply shocked" by the attacks and pledged solidarity with France in combating terrorism.
In New York, the One World Trade Center spire is lit blue, white and red in a symbol of solidarity with Paris.
