SEOUL, March 14. /TASS/. South Korea and the US have detected signs that North Korea is preparing to conduct another intercontinental ballistic missile (ICBM) system test as early as this week, the Yonhap news agency reported on Monday.

"Though we can’t say definitively when a missile will be launched, we have been keeping close tabs on the possibility," a government source told Yonhap News Agency. An official at Seoul’s Joint Chiefs of Staff refused to make "prejudgment" but stressed South Korea’s "robust" readiness posture.

It is stated that weather conditions and other variables are expected to affect the timing of Pyongyang’s possible launch.

On March 11, Washington and Seoul announced that Pyongyang had tested ICBM system on February 27 and March 5.
