President Moon Jae-in has reportedly hit the ceiling after being informed that there are four more US Terminal High Altitude Area Defense (THAAD) anti-missile launchers in South Korea than he had previously been told.

Korea JoonAng Daily says that Moon has ordered a thorough investigation into the South Korean Defense Ministry’s failure to brief his transition team about the US military’s in-country storage of additional launchers for THAAD.

“The president was briefed that four launchers, in addition to the two already installed in Seongju, were clandestinely brought in and stored in Korea,” Yoon Young-chan, senior secretary for public relations, reportedly said Tuesday. “Today, Moon ordered his senior secretary for civil affairs and chief of the national security office to conduct a thorough investigation over how the four additional launchers were brought in.”
