Security Raised After Attack on Airport

Alarmed by a rocket attack on the New Tokyo International Airport at Narita days before the start of the Olympics, police sharply heightened surveillance at the airport and stepped up security at the Winter Games in Nagano. The attack Monday came as foreign athletes, officials and spectators were streaming through the airport on their way to the Games, which start Saturday. Police have no evidence so far that the rockets, which injured a worker, were linked to the Olympics. Authorities suspect that the attack 40 miles east of Tokyo was carried out by radicals who have long opposed the building of a second runway.
