North Korea appears to have moved an intermediate-range missile to its east coast, but there are no signs of an imminent launch, Reuters reports citing South Korea's Yonhap news reported.

The North Korea missile is presumed to be a Musudan, an unnamed government source said, the same missile it attempted to launch in May.

Japan's military is on alert for a possible North Korean ballistic missile launch, a government source said on Tuesday, June 21 with local media reporting its navy and anti-missile Patriot batteries have been told to shoot down any projectile heading for Japan.
