TOKYO (AP) — Sebastian Coe tried to reassure athletes and skeptical residents of Japan that the postponed Olympics will be safe when they open in just under 11 weeks. Coe is the head of the world governing body of track and field. He helped Japanese officials run a meet at the new National Stadium this weekend. It serves as a test event for the Olympics. The scene was different outside the stadium where a few hundred “anti-Olympic” protesters marched around the venue in central Tokyo chanting and holding posters that read: “Olympics Kill The Poor” and “Olympics — Just Stop It.” The Olympics open on July 23.
