Two men who French police are seeking to trace in connection with the Paris attacks registered as refugees with Greek authorities earlier this year, the Greek police confirmed on Saturday.

French authorities had asked their Greek counterparts to check a passport and fingerprints of one man and the fingerprints of another who were thought to have registered in Greece, which is the main entry point into Europe for Syrian refugees.

At least one Syrian passport was found near the body of one of the seven assailants who died in Friday night's violence.
