Residents of a coastal town held evacuation drills Saturday to prepare for any launch of North Korean missiles toward the U.S. Pacific territory of Guam, in case they fly over their homes.

As sirens blared from speakers in the town of Kotoura, Tottori Prefecture, children playing soccer outside ran to take shelter in a school, along with their parents and their team coach.

"I've been concerned every day that something might fall or a missile could fall in an unexpected place due to North Korea's missile capabilities," said the coach, Akira Hamakawa, 38.
