Pyongyang launches missiles, South Korea and US reply.

(RT) ⸻ South Korea and the US staged combined air drills on Sunday, a day after North Korea fired a long-range ballistic missile into the sea. South Korean F-35A and F-15K fighters, and US F-16s escorted American B-1B aircraft entering the South's air defense identification zone. The drills demonstrated the South Korea-US combined defense capabilities and posture featuring the alliance's overwhelming forces, and affirmed the US' "ironclad" commitment to defending South Korea and its extended deterrence pledge. North Korea has vowed to come up with an "unprecedentedly persistent, strong" response to upcoming joint drills.
