South Korean President Moon Jae-in on Monday ordered an additional probe into the unreported deployment of four more mobile launchers of the US missile shield into the country.

Moon ordered an investigation into the "intentional" omission of a report to the new leader about the deployment of four THAAD mobile launchers, which were dispatched to an unidentified US military base in South Korea.

The findings showed Wi Seung-ho, chief of the defense ministry's national defense policy office, ordered officials to omit details of the deployment of four more THAAD launchers from a document to the presidential Blue House.

Wi will be excluded from relevant defense affairs, while other relevant defense ministry officials will be subject to further investigations, according to the Blue House.

President Moon also ordered a separate probe into the defense ministry, amid suspicions that the ministry avoided conducting an environmental assessment on the US missile defense system at a golf course in Seongju county, North Gyeongsang province.
