The jihadi, who blew himself up on the streets of the French capital during the attacks that killed at least 129 people, claimed asylum in Greece last month with a fake Syrian passport bearing the name Ahmad Almohammad. Serbian authorities said they arrested a man carrying a passport with the same name, date of birth and place of birth and claimed up to six more men had entered the EU with remarkably similar authorisation.

The shocking assertions have sparked fears that ISIS extremists planning deadly attacks across Europe could be roaming free anywhere in the EU’s passport-free Schengen area. Lord Green of Deddington, the chairman of campaign group Migrationwatch, said: “This underlines the extent to which the southern borders of the EU is now wide open to fraud. “It will take a huge operation to recover any controls worth the name. Meanwhile, the security risks of people carrying bogus passports around Europe speaks for itself.”

Around 670,000 asylum seekers have arrived in Greece this year after fleeing the atrocities in Syria and the Middle East, leaving officials worried as to how many ISIS militants could have crept into the continent too. The fingerprints of the militant who tried to attack the Stade de France matched those of a migrant who passed through Greece in October. Authorities confirmed the same passport-holder passed through a refugee camp near the Serbian border with Macedonia. Home affairs select committee member, James Berry, said: “In the UK we have the reassurance that we are not full members of the Schengen agreement so the passports of all people travelling here are checked thoroughly. “But Europe is too porous – if terrorists get though the initial border then there are no further checks before they get to the place they want to attack.”

Travel document forgers will reportedly provide fake Syrian passports, ID cards or birth certificates for as little as £165. Chairman of the home affairs select committee, Keith Vaz, said: “We need to urgently provide EU countries on the southern border with the equipment and expertise to deal with this immigration fraud. “To fail to do so will put the lives of EU citizens at risk.” French authorities believe the documents found on one of the Paris attackers probably belonged to a Syrian soldier killed several months ago.
