North Korea fired several rounds of unidentified short-range "projectiles" into the Sea of Japan on Saturday, the South Korean Joint Chiefs of Staff said.

The North "fired multiple rounds of unidentified projectiles from its east coast town of Wonsan in the northeastern direction between 9:06 a.m. and 9:27 a.m. today," the JCS said in a release. They flew for a range of about 70 kilometers to 200 kilometers, the JCS said.

Japan's Defense Ministry said the projectiles did not reach anywhere near the country's coast and that Japan is not facing any security threat. The ministry said it has not detected signs that any of the projectiles fired Saturday reached in or around the country's territory or its 200-nautical-mile (320-kilometer) exclusive economic zone.
