N. Korea deploys ballistic missile to east coast: source

North Korea has deployed an intermediate-range ballistic missile to its east coast although there are no signs it's ready for launch, a South Korean government source said Tuesday.

"We have detected signs that the North has deployed what appears to be a Musudan missile," the source said on the condition of anonymity.

A South Korean military official said the military is closely watching the situation.

Earlier, Japan's Kyodo news agency reported the North is preparing to fire a missile. (Yonhap)
