One of the suicide bombers at a packed sports stadium in Paris on Friday entered Europe on a boat with migrants, according to Greek officials, NBC News reported.
The man, who was carrying a Syrian passport, gave his name as Ahmad Almohammad to officials when he landed on the Greek island of Leros in October. French justice minister Christiane Taubira told NBC News the passport was likely not genuine.
Fingerprints taken by Greek authorities match one of the three attackers who blew themselves up outside the stadium during a soccer match on Friday, according to NBC News.
Another of the seven dead attackers was identified as Sami Amimour, 28, a French native known to anti-terror police, was among the attackers at the Bataclan concert hall.
On Monday, French officials said the attacks were masterminded by Abdelhamid Abaaoud, a Belgian with known terror connections, NBC News reported.
