Paris attacks put a focus on border security
THE effects of the attack on Paris will be felt across the whole of Europe with an emphasis on the influx of migrants from the Middle East.
Several European Union countries also indicated they would impose restrictions on the Schengen Agreement, which guarantees free movement across most of the bloc.
At least one of the Paris terrorists had registered as a refugee with Greek authorities earlier this year.
French authorities had asked their Greek counterparts to check the fingerprints of one man who died in the attacks, with a Syrian passport found next to him, in addition to the fingerprints of another man.
The Greek Minister for Citizen Protection Nikos Toskas said one man had been registered on the Greek island of Leros in October.
Mr Toskas said the man "was registered under EU rules".
Marine Le Pen, the leader of France's far right Front National, has constantly referred to the dangers of migration.
Ms Le Pen went on to advocate that France regain control of its borders and expel "illegal migrants".
After France closed its borders, other EU countries reacted by upping security.
Belgium, Holland and Poland all imposed controls on their borders.
In Germany, Markus Soder, the Bavarian Government's finance minister, said "the days of unchecked immigration and illegal entry can't continue. Paris changes everything".
