More Than 120 people Killed In Paris

When attackers killed more than 120 people in Paris on Friday, it set off police raids, arrests and other detentions in France, airstrikes in Syria against ISIS and condemnation around the world.

Here is what we know so far from officials and local news reports:

-- Police blocked roads in the Brussels, Belgium, suburb of Molebeek, reputedly frequented by extremists, ahead of a possible detention. Police in balaclavas surrounded a building and called over a megaphone for someone to come out.

-- French Interior Minister Bernard Cazaneuve said "war" had been declared on France, and that "Anybody who attacks the Republic, the Republic will fight back."

-- Twenty-three people are in custody and weapons and IT equipment have been seized, Cazaneuve said. A rocket launcher and bulletproof vest were among the items seized.

-- Cazenueve has ordered 104 people to be put under house arrest since the Paris attacks.

-- More than 150 police anti-terror raids conducted in cities across France.

-- A fourth attacker has been identified from the Bataclan massacre as Samy Amimour, 28, the Paris prosecutors office announced.

-- A worldwide manhunt is underway for Belgian-born French national Salah Abdeslam, who is suspected of being involved in the attacks. French police warned that he is "dangerous."

-- Three teams of terrorists staged coordinated attacks at six locations throughout Paris late Friday, including a concert hall, the Stade de France and at least two restaurants, Paris prosecutor Francois Molins said Saturday.

-- Molins said that at least 129 people were killed and 352 wounded in the attacks. Ninety-nine of the wounded are reported to be in a very serious condition, he said.

-- Molins said seven terrorists were killed, one fewer than the number ISIS claimed were involved.

-- Two of the dead attackers were identified as Ismael Omar Mostefai, 29, and Bilal Hafdi, 19 or 20.

-- Six of Mostefai's relatives have been detained, the Paris prosecutor's office said Sunday. It is common practice in criminal cases in France, even though none of them has been charged or arrested.

-- Three of Amimour's relatives are in the same type of custody.

-- A black Seat and a black Volkswagen Polo, which is registered in Belgium, appear to be two cars used in the Paris attacks. The Polo was rented by a French nationalliving in Belgium, who was intercepted at the Belgian border inside a different vehicle.

-- The black Seat was found in the eastern Paris suburb of Montreuil. CNN affiliate BFMTV reported that authorities found three Kalashnikov automatic rifles in the car.

-- The discovery raises the possibility that at least one attacker drove the car to Montreuil and remains at large.

-- European officials believe professional terrorists are joining migrant voyages. One of the suicide bombers at the Stade de France was carrying a fake Syrian passport and arrived among the refugees on the Greek island of Leros on October 3.

-- U.S. intelligence and law enforcement officials are concerned the Paris attackers "went dark," i.e., used encrypted communications to avoid surveillance.

-- This was the deadliest site, with at least 89 people killed.

-- Three attackers with assault rifles arrived in a car, entered the concert venue and opened fire.

-- A witness told Radio France that the attackers entered firing pump rifles and shouting "Allahu akbar."

-- They took audience members hostage and regrouped them in front of the stage, where most of the victims were found. The attackers talked about Syria and Iraq during a brief address.

-- Police stormed the theater in a rescue operation. Two of the attackers killed themselves by detonating suicide belts and one was killed by police gunfire and his suicide belt.

-- Four people were killed outside the sports stadium in Saint-Denis, a suburb north of Paris: three suicide bombers and a man who had been walking by.

-- France was playing Germany in a soccer match at the time.

-- President Francois Hollande was at the stadium and among those who were evacuated following the attacks.

-- Fifteen people were killed as attackers opened fire at an intersection where the restaurant Le Petit Cambodge and the bar Le Carillon are located.

-- About seven minutes later, five people were killed in another shooting outside Cafe Bonne Biere.

-- Around four minutes after that, attackers opened fire with assault weapons on the restaurant La Belle Equipe. Nineteen people were killed in that shooting.

-- Four minutes later, a suicide bomber blew himself up at the cafe Comptoir Voltaire on Boulevard Voltaire. Only the attacker was killed, but one person was critically wounded.

-- President Hollande declared a state of emergency across France, which lets authorities limit people's movements and impose zones of security and protection.

-- The French government announced tightened border controls and put the gendarmerie paramilitary police on heightened alert.

-- Hollande ordered 1,500 military troops to join already increased security forces.

-- Sources told CNN that Abdeslam was stopped and questioned by French police shortly after the attacks. At the time, he was not a suspect. He was let go.

-- The French Air Force carried out bombing missions over Raqqa Sunday and Monday against strategic ISIS targets.

-- Prior to Friday's attacks, Iraq shared intelligence that ISIS leader Abu Bakr al-Baghdadi had ordered an attack on countries fighting against ISIS. There were no specifics about when or where the attack would take place.

-- U.S. President Barack Obama pledged solidarity with France, saying, "We've seen an outrageous attempt to terrorize innocent civilians."

-- Pope Francis condemned the killings, saying they were a part of the "piecemeal Third World War."

-- British Prime Minister David Cameron convened a meeting of the emergency response committee.

-- Russian leader Vladimir Putin sent condolences to Hollande and the people of France.
