North Korean leader Kim Jong Un oversaw a test of short-range ballistic missiles and long-range artillery in a demonstration of Pyongyang's nuclear counterstrike capabilities, state-run media said Friday.

North Korea has fired various types of short-range ballistic missiles into its eastern sea, according to South Korea's military, which was analyzing whether the tests were linked to the North’s weapons exports to Russia amid the prolonged aggression in Ukraine.

The test, which also included an inspection of the operational reliability of its "nuclear trigger" system, was designed to ensure the rapid response posture to counter the sensitive regional military climate,
