Republic of Korea (ROK) President Moon Jae-in on Saturday proposed a set of tough countermeasures following the latest ballistic missile launch by the Democratic People's Republic of Korea (DPRK), including the deployment of an additional four Terminal High Altitude Area Defense (THAAD) launchers, reported Yonhap citing the president's office.

It came after Pyongyang conducted an intercontinental ballistic missile test late on Friday night. 

Two THAAD interceptor launchers are in operation at a former golf course in Seongju, some 300 kilometers southeast of Seoul, with four others stored at a nearby US military base.

Meanwhile, the ROK and US conducted a live-fire exercise after the launch of the intercontinental ballistic missile by the DPRK on Friday, said the US Army.
