North Korea fires 10 short-range surface-to-surface ballistic missiles Frog-7 into East Sea 1703142.

Recently, Pyongyang fired 25 short-range rockets into waters off its east coast Sunday evening, which flew about 70 kilometers. The South Korean military judged the rockets to be FROG-7 short-range surface-to-surface missiles.

Sunday's rocket launch came two days after the North's National Defense Commission threatened to demonstrate its nuclear deterrence capability against the U.S. hostility.

South Korean military is considering this to be North Korea's firing demonstration, as an armed protest responding to Korea-US joint military exercises, and is additionally analyzing its specific intention.

Pyongyang routinely condemns such war games as rehearsals for an invasion, while Seoul and Washington maintain that they are purely defensive.

Since the drills began, North Korea has held several rounds of short-range missile launches.
