Alert levels and surveillance are ramped up in South Korea on Wednesday as officials say North Korea may launch a missile "at any time."
SEOUL, South Korea/WASHINGTON — South Korea said Wednesday there was "very high" probability that North Korea, engaged in weeks of threats of war, would launch a medium-range missile at any time as a show of strength despite diplomatic efforts to soften its position.
The U.S.-South Korea Combined Forces Command in Seoul, South Korea, raised its "Watchcon 3" status, a normal condition, by one level to boost monitoring and increase the number of intelligence staff, a senior military official told the South's Yonhap news agency.
Foreign Minister Yun Byung-se told a South Korean parliamentary hearing: "According to intelligence obtained by our side and the U.S., the possibility of a missile launch by North Korea is very high."
North Korea, he said, could launch a Musudan missile "at any time from now."
Yun said he was coordinating with China and Russia "to make efforts to persuade North Korea to change its attitude."
China is North Korea's sole major ally, although its influence over Pyongyang is open to question and Beijing has, in any event, backed the new sanctions. Moscow backed North Korea in Soviet times, though its influence has waned unquestionably.
Yun said South Korea had asked China and Russia to intercede with the North to ease tension that has mounted since the U.N. Security Council slapped fresh sanctions on Pyongyang after a new nuclear arms test in February.
But all was calm in the South Korean capital, Seoul, long used to North Korean invective under its 30-year-old leader Kim Jong Un. Offices worked normally and customers crowded into city-center cafes.
Other officials in Seoul said surveillance of North Korean activity had been enhanced. Missile transporters had been spotted in South Hamgyong province along North Korea's east coast — possible sites for a launch.
North Korea observes several anniversaries in the next few days and they could be pretexts for military displays of strength. These include the first anniversary of Kim's formal ascent to power, the 20th anniversary of rule by his father Kim Jong Il, who died in 2011, and the birth date next Monday of his grandfather, state founder Kim Il Sung.
The near-daily threats to South Korea and the United States in recent weeks were muted in state media Wednesday, with the focus largely on the festivities lying ahead.
In Washington, Adm. Samuel Locklear, the commander of U.S. forces in the Pacific region, also said the U.S. military believed North Korea had moved an unspecified number of Musudan missiles to its east coast.
The Musudan can reach targets at a distance of 2,100 miles or more, according to South Korea, which would put Japan within range and may even threaten Guam, home to U.S. bases. South Korea can be reached by the North's short-range Scud missiles.
Patricia Lewis, research director at the London-based think tank Chatham House, said that strictly on the basis of the North's vast conventional forces, caution was required.
"The conventional military capabilities of North Korea are all too real and all too close to Seoul," she wrote in a paper. "Any incursion could escalate involving the U.S. and Japan, China, perhaps Russia and others."
Pyongyang has tested short-range Scud missiles. The longer-range Musudan and Nodong missiles are an unknown quantity.
"If the missile was in defense of the homeland, I would certainly recommend that action (of intercepting it). And if it was defense of our allies, I would recommend that action," Locklear told a Senate hearing in Washington.
Pyongyang has threatened a nuclear strike on the United States — something it does not have the capacity to carry out — and "war" with "puppet" South Korea — threats that appear to be aimed at least in part at boosting internal support for Kim.
