Fingerprints have revealed that two of the Stade de France suicide bombers had entered Europe through Greece last month.
The France v Germany friendly international football match was abandoned after three jihadists blew themselves up outside the ground, as part of a number of attacks in Paris which killed 130 people.
At least one suicide bomber had a ticket to the Stade de France and wanted to enter the stadium before exploding, but was rejected by a security officer.
Thousands of fans ran onto the pitch at the country’s national stadium after the explosions went off.
It has now emerged that two of the ISIS militants were checked by Greek authorities on October 3, according to prosecutors in the French capital.
