South Korea has reportedly conducted military exercises after Pyongyang’s latest nuclear test, according to multiple news outlets.
The training exercises, led by South Korea’s Army and Air Force, simulated a strike against its neighbor with F-15K fighter jets hitting targets as well as surface-to-surface ballistic missiles, CNN reports. The drills, which took place early Monday morning local time, included a simulated strike on North Korea’s nuclear test site, Punggye-ri.
The exercises come hours after North Korean state media announced the country had successfully tested a miniaturized hydrogen bomb capable of fitting on an intercontinental ballistic missile (ICBM).
Defense Secretary James Mattis responded by warning Pyongyang it would be met with a “massive military response” if it threatened the U.S. or its allies.
“Any threat to the United States or its territories including Guam or our allies will be met with a massive military response,” Mattis said, following a meeting with President Donald Trump.
Trump last month pledged that North Korea would face “fire and fury” if it continued to threaten the U.S. and its allies. After North Korea launched an ICBM over Japanese airspace last week, Trump also noted that reasoning with the Pyongyang is no longer a solution.
