North Korea confirms 2nd test of multiple rocket launcher

North Korea says leader Kim Jong Un observed the test-launch of a multiple rocket launcher, the latest weapons test performed amid stalled diplomacy over the North's nuclear program

SEOUL, South Korea -- North Korea said Wednesday leader Kim Jong Un observed the test-launch of a super-large multiple rocket launcher, the latest in a series of weapons tests performed amid stalled diplomacy over the North's nuclear program.

Some experts said North Korea aims to wrest concessions from the United States once their diplomacy resumes.

The North's Korean Central News Agency said Kim, accompanied by top military and ruling Workers' Party officials, supervised the two rounds of test-firings at an unidentified place on Tuesday.

It was the second known test of a super-large multiple rocket launcher that North Korea says is needed to cope with outside military threats. The first test of the weapon occurred on Aug. 24.

Tuesday's test fulfilled its purpose and allowed authorities to decide "the next-stage orientation to complete the weapon system," KCNA said. It quoted Kim as saying what remains to be done is "running fire test."

Tuesday's weapons test was the eighth round of launches by North Korea since late July. Other weapons tested include at least three other newly developed short-range missile and rocket artillery systems that experts say would potentially expand its capabilities to strike targets throughout South Korea. South Korea's military said the two North Korean projectiles fired Tuesday flew about 330 kilometers (205 miles) in the direction of the waters off the North's east coast.

The North Korean weapons tested in the past weeks were all short-range, and the country is still keeping its promise not to carry out nuclear and long-range missile tests. This suggests North Korea is trying to maintain the momentum for dialogue with the United States, experts say.
