South Korea’s military fired multiple missile systems as part of a live-fire exercise in response to North Korea’s test of an intercontinental ballistic missile on Thursday, according to Seoul’s Joint Chief of Staff (JCS).

The “joint ground-sea-air missile” live-fire was conducted from the East Sea from 4:25 p.m., JCS said in a text message to journalists. The measure comes after the DPRK launched an ICBM from the Sunan area near Pyongyang at 2:34 p.m., with the missile reaching an altitude of more than 6,200 km and covering a range of 1,080 km, according to the South Korean military.
