Seoul, Washington monitoring possible N. Korea missile test - Yonhap

South Korea’s Yonhap news agency reported comments from the South Korean Army Col. Roh Jae-cheon, the spokesman of the Joints Chiefs of Staff, noting that South Korea and the United States are closely watching the possibility of North Korea resuming provocative acts.

Army Col. Roh Jae-cheon said: "The South Korean military is closely monitoring and tracking possible North Korean provocations in collaboration with the U.S."

His comments come after the Japanese government source reported on Tuesday that Japan has detected radio signals suggesting North Korea may be preparing for another ballistic missile launch.
