North Korea has conducted a second day of short-range rocket launches, apparently to protest joint military exercises between South Korea and the United States.
South Korea's Joint Chiefs of Staff said the North fired 16 short-range rockets into its eastern waters in the early hours of Sunday, following similar launches of 30 rockets early Saturday.
A South Korean military spokesman said the rockets have a range of about 60 kilometers, adding that they were old versions of Russian-made unguided FROG rockets.
Analysts say the launches are an expression of Pyongyang's anger at ongoing annual South Korean - U.S. military drills, which run until next month.
The North routinely criticizes the drills, saying they are rehearsals for an invasion.
