One of the more complicated stories to emerge from the Nov. 13 Paris terror attacks has concerned "Ahmad al-Mohammad," which is the name on a fake Syrian passport that was found near the remains of one of the three attackers who detonated suicide bombs in the area of the Stade de France stadium. Fingerprint evidence is said to indicate that, while his documentation was not legit, the man who used the passport did pass through a Greek refugee facility in October. Today, Paris prosecutor François Molins said in a statement that there's evidence that another one of the Stade de France bombers was in Greece at the same time (translation via the Guardian):
A new Stade de France suicide bomber, who blew himself up at 21.30pm on Rue Rimet, H Door in St Denis, was formally identified and his fingerprints matched those of someone who passed through Greece on the 3 October 2015.
It was during this same immigration check that the other suicide bomber who blew himself up at 21.20pm at D door of the Stade de France had his fingerprints registered.
The other identified perpetrators of the Nov. 21 attacks were French nationals; purported attack planner Abdelhamid Abaaoud, who was killed this week, was Belgian.
