North Korea launched multiple ballistic missiles toward the sea off its east coast on Sunday morning, according to South Korea's Joint Chiefs of Staff.

The missiles were fired from North Korea's eastern Sinpo area, South Korean military officials reported. The launches were directed toward the waters off North Korea's eastern coastline.

South Korea's military is analyzing the details of the missile launches, including the exact number and specifications of the projectiles fired. The Joint Chiefs of Staff confirmed the launches occurred Sunday morning local time.

The Sinpo area on North Korea's east coast has been used previously for missile testing activities. North Korean missile launches toward surrounding waters are routinely monitored by South Korean and other regional military forces.

South Korean authorities have not yet released additional details about the range, flight duration, or other technical characteristics of the missiles launched.
