AKIPRESS.COM - North Korea fired three ballistic missiles Monday morning, according to South Korea's military, CNN reports.

The missiles were fired from areas around Hwangju county, in North Hwanghae province, toward the Sea of Japan, South Korea's military said.

Officials said the launch was believed to be of midrange Rodong missiles, which flew about 1,000 kilometers (620 miles) "without giving any prior navigational warning."

North Korean leader Kim Jong Un "expressed great satisfaction" over the launch and called on his country to bolster its nuclear forces, according to a report on Tuesday in the state-run KCNA news agency.

It comes just under two weeks after Pyongyang test-fired a submarine-launched ballistic missile.

That missile entered Japan's air defense identification zone, the first time that has happened. Monday's launch also fired missiles into the Japanese defense zone, again without warning.
