One of the suspects in Friday's Paris deadly terrorist attacks that shocked the world had recently passed through Greece, the Greek Public Order ministry said in an announcement on Saturday.

"The holder of the Syrian passport which was found on the site of the terrorist attack (at Stade de France) passed through Leros island on October 3, 2015 and was registered under the EU regulations, according to the EU Summit's decisions on the management of the refugee crisis," Deputy Public Order Minister Nikos Toskas said in written statement.

"We do not know whether the passport was checked by other countries ... We will continue effort to safeguard the security of our country and Europe's under difficult circumstances," he added.

According to unconfirmed Greek government sources French authorities requested earlier on Saturday information from Athens on two suspects following the attacks which have left more than 120 dead and 200 injured. The one with the Syrian passport was found dead in the Parisian stadium.

More than 600,000 refugees and migrants have reached Greece's shores from the start of this year with the vast majority being Syrians fleeing the war. Most of the refugees after their registration on the Greek islands continue their journey to western and northern Europe.
