March 14 (UPI) -- North Korea launched 10 ballistic missiles into the sea on Saturday -- which landed just outside Japan's economic zone in the East Sea -- in a show of force amid a U.S.-South Korea military exercise.

The launch, confirmed by the Japanese and South Korean defense ministries, is one of the largest North Korea shows of force that it has ever launched, The Japan Times and The Independent reported.

The missiles were launched from the west coast of North Korea, flying roughly 211 miles before falling just outside the Sea of Japan.

The Japanese Ministry of Defense in a statement called the launch a continued effort to "threaten the peace and security of Japan, the region and the international community."
