Saitama Super Arena is expected to host basketball games during the 2020 Olympics.Drill participants practiced responding to a supposed bomb explosion near spectator seats that killed and injured many. Firefighters and doctors rescued and treated the victims.
About 40 minutes later, police officers located a drone supposedly loaded with explosives that had crashed near the arena.
The officers first used a remote-controlled robot to determine whether the drone was emitting radiation. Then members of a bomb squad wearing protective suits used a robot to carefully dispose of the small aircraft.
