The 1987 Greece bus attacks refer to two separate attacks committed by the 17 November Group on buses carrying American military personnel near Athens, Greece. The first attack, on April 24, 1987, wounded 16 Americans (four of which were civilians) and two Greeks (the bus driver and a civilian car driver nearby). A Hellenic Air Force bus was transporting American servicemen from a Greek base to the American-operated Hellenikon Air Base when a remote-controlled car bomb exploded, causing the bus to lose control and hit a tree. It was initially reported the bus was hit by a rocket attack. The chief of Greece's police called it a "well-planned crime". Greek Prime Minister Andreas Papandreou condemned the attack.
