SOUTH KOREAN President Moon Jae In demanded a probe yesterday into why he wasn’t told about the arrival of additional launchers for the country’s US-supplied terminal high-altitude area defence (Thaad) missile defence system.

President Moon vowed before taking office on May 10 to review deployment of a system that has infuriated both North Korea and China, which consider its powerful radar a security threat.

Many of his supporters don’t want the system, which US President Donald Trump said Seoul should pay for.
