Title: News Title-크로마 Title: Opening Good to have you with us, I'm Daniel Choy for Arirang's weekend news. Title: S. Korean military mobilizing for search after third crashed N. Korean drone found South Korean soldiers found another crashed drone on a mountain in Samcheok, 290 kilometers east of Seoul, earlier this Sunday. This is the third such discovery so far and all three drones are identical in appearance. South Korea will mobilize units across the country to search for other drones. Defense Minister Kim Kwan-jin says Pyongyang could be developing more-advanced unmanned aerial vehicles for attack purposes. The range of these drones is 800 kilometers, close enough to strike major South Korean and U.S. military targets. The South Korean military is considering purchasing advanced low-altitude surveillance radar systems and anti-aircraft guns to better detect small aircraft and shoot them down. Title: Pyongyang's new nuke test type could be simultaneous detonation: 38 North A North Korea expert has suggested that... in carrying out its recent threat to conduct a new type of nuclear test,.... Pyongyang may try detonating multiple bombs simultaneously. Our defense ministry correspondent Kim Hyun-bin reports. North Korea expert Jeffrey Lewis said Saturday on the website 38 North that the main question about Pyongyang's threat to conduct a fourth nuclear test is not what but how the test will be carried out. He highlighted North Korea's response to the UN Security Council's condemnation of its ballistic missile launches last week, when Pyongyang said it will bolster its nuclear deterrence with a new kind of nuclear test. Lewis said he believes the test will be conducted with simultaneous detonation of other nuclear devices. He pointed out that Russia and the U.S. have conducted simultaneous detonations of up to five nuclear bombs, and compared the North's current situation to that of the Soviet Union. Like the Soviet Union, Pyongyang lacks nuclear facilities, suffers financial issues and has to deal with unpredictable weather. He also pointed to the possibility of vertical tunnel testing. The current test site at Punggye-ri has horizontal tunnels in the mountains near the site, but the size of the bombs Pyongyang can test is limited by the size of the mountains and the resulting overburden, and he said the test site could only accommodate few tens of kilotons. He pointed out that larger tests would need to be done in tunnels drilled much deeper into the ground. He also suggested that atmospheric and thermonuclear tests are a possibility. Atmospheric nuclear tests are prohibited under the Limited Test Ban and the Comprehensive Nuclear Test Ban Treaties but North Korea has neglected to sign both. Lewis says Pyongyang is unlikely to conduct an atmospheric test, as it would anger the Chinese public. North Korea has conducted three nuclear tests so far -- in 2006, 2009 and February of 2013.

Title: Three sailors from sunken Mongolian cargo ship rescued and repatriated And now on to the latest in a search for survivors following the sinking of a Mongolian cargo ship... South Korea's Coast Guard on Sunday... saved the lives of three of the 16 North Korean sailors on board... after a search and rescue operation that lasted three straight days. The three sailors and the bodies of two others who died in the incident were returned to the North today. The repatriation took place at the truce village of Panmunjom inside a military buffer zone that separates the two Koreas, according to a South Korean government official. The Mongolian-flagged cargo ship sank some 63 kilometers off the coast of South Korea's southern city of Yeosu on Friday. 11 other crew members are still missing. Title: U.S. to deply 2 additional Aegis destroyers to Japan by 2017: Hagel U.S. Secretary of Defense Chuck Hagel has announced plans to deploy two additional Aegis destroyers to Japan by 2017. Hagel, who is currently in Japan, met with his Japanese counterpart Itsunori Onodera on Sunday and said the deployment is in response to Pyongyang's pattern of provocative and destabilizing actions, including recent missile launches in violation of UN Security Council resolutions. Last year, the U.S. decided to deploy a second missile-tracking radar system in Japan and additional interceptor systems in Alaska to counter the North's ballistic missiles.
