Three teams of terrorists carried out the coordinated deadly assaults in and around Paris Friday night that killed at least 129, the city prosecutor's office said Saturday. At minimum, three of the seven men known to have been involved held Belgian or French passports.

The terrorist attacks took place at several different locations, including the Bataclan concert hall, the Stade de France soccer stadium and several restaurants. The terrorist used automatic weapons to shoot people at all the sites, except the Stade de France where they detonated explosive vests. At the Bataclan theater, they killed at least 89 people at a performance by U.S. rock band Eagles of Death Metal and took hundreds of others hostage for several hours.

The attackers struck seven times in quick succession, Paris prosecutor Francois Molins said Saturday. The shooters were armed with Kalashnikov automatic weapons, and all the terrorist wore identical vests loaded with explosives.

Information about the nationalities of the terrorists is still surfacing, with the evidence indicating they had ties to to Egypt and Syria, as well as Belgium and France. "A Syrian passport in the name of a person born in Syria in September 1990 was found near a suicide bomber who blew himself up at the Stade de France," Molins told reporters.

One of the men involved in the attack outside the Stade de France where suicide bombers detonated explosives was a Syrian national. A Greek government official said the name on the Syrian passport found near the bomber’s remains matched that of a Syrian asylum seeker who registered in Greece this year. At least one of the attackers was a French national who grew up in a town 20 miles south of Paris.

Police at the Belgian border stopped a man with a car associated with the assaults, and Belgian police have arrested at least three people in connection with the attacks, Sky News reported.

Meanwhile, French authorities have warned that accomplices to the crimes may still be at large.
