South Korea's Defense Ministry on Tuesday (May 7) did not confirm North Korean missile movement but said it was continuing to monitor the North's activities.
On Monday (May 6), U.S. officials said that North Korea took two Musudan missiles off launch-ready status and moved them from their position on the country's east coast.
U.S. Secretary of State John Kerry warned North Korea last month that it would be a "huge mistake" to launch the medium-range missiles, but the prospects of a test had put Seoul, Washington and Toyko on edge.
The Musudan missiles have a range of roughly 3,000 to 3,500 kilometers (1,900 to 2,200 miles). A possible test launch, depending its trajectory, could have dramatically escalated tensions on the Korean peninsula.
North Korea's move coincided with preparations by President Barack Obama to meet South Korean President Park Guen-hye at the White House on Tuesday, where they will hold talks and have a working lunch followed by a joint news conference..
