North Korea fired 16 short-range rockets from its east coast early Sunday for a second straight day, the Joint Chiefs of Staff (JCS) said, the latest in a series of provocative launches that are in apparent protest of ongoing joint military drills between Seoul and Washington. The North fired 30 FROG ground-to-ground rockets from the eastern city of Wonsan, the same test site, early Saturday, without making a pre-announcement for civilian flights or vessels.
