As has occurred in most Western countries since the Sept. 11 terrorist attacks, security is going to be increased in Greece in the days ahead. The Athens airport, public buildings, ministries, power and telecommunications facilities, ports and cruise ships will all see tighter security arrangements. The borders and all islands near the Turkish coast will be guarded more carefully. Existing emergency plans for fighting terrorism will be implemented as one of the new security measures. As in the U.S., expect delays when traveling.
