Police have identified the first of the Paris assassins

François Molins, the Paris Prosecutor, has announced that French investigators have identified the first of the assassins who killed 129 people in Friday in Paris during a coordinated attack. Omar Ismail Mostefai (age 29) was identifed by one of his fingers that was found at the Bataclan concert hall.

Mostefai lived in a suburb of Paris and was one of the men who committed a suicide assassination targeting those attending a rock concert at the Bataclan center. A police source told Agence France-Presse that their first order of business is to identify the other assassins.

Officers will then ascertain whether the assailants had accomplices. A spokesperson for the Office of the Paris Prosecutor announced that French Police also arrested the brother and father last night of another of the terrorists who attacked in Paris on Friday.

The spokesperson said police are searching the building where those persons were arrested but did not provide further details. Meanwhile, the Belgian Government has announced that it is increasing its security measures for large-scale events from the second level of alert to level three.

The Belgian cabinet said this maximum police readiness especially concerns entertainment events and sports venues. The measures were adopted during a nighttime session of Belgium’s Security Council after it developed that the tracks of the organizers of Friday’s terrorist action in Paris might lead to Belgium.

Among the victims of Friday’s terrorist action, according to unofficial reports, are the citizens of 12 states. Those who have perished are said to include one American, two Tunisians, one Swede, two Mexicans, one Spaniard, two Romanians, two Portuguese, one Moroccan, two Chileans, one Briton, three Belgians and one Algerian.

Was one of the assassins a "refugee"?

Authorities say a Syrian passport was found near the body of one of the deceased assassins. According to the Greek authorities, the number of the passport corresponds to a man who registered as a refugee at the beginning of October when he entered that country.

Czech news server iDNES.cz reports that doubt has been cast on that information, however, by a member of the security services who told the American broadcaster CBS News that the passport may have been faked. The identification number of the document reportedly does not correspond to the numbering used on Syrian documents, and the name on the document is said to not correspond to the man depicted in the photograph.
