A phone call announcing the existence of an explosive device at the General Secretariat of Macedonia-Thrace in Thessaloniki on Friday night proved to be a hoax.

The phone call was made to police shortly before 10 at night and police immediately cordoned off the building and the surrounding streets, while bomb disposal experts moved in with sniffer dogs but the ensuing search of the premises revealed nothing and about an hour later the streets were reopened to traffic.
