At approximately 1700 local time (0800 UTC) on 14 October 2022, the North Korean military fired approximately 200 artillery rounds into maritime buffer zones near North and South Korea’s western sea boundary. In addition, 80 artillery rounds were fired into waters near the countries’ eastern sea boundary. None of the shells fell in South Korean territorial waters. The maritime buffer zones — where the artillery shells landed — were established between the two rivals in 2018 to prevent accidental conflict. Earlier in the day, at least 10 North Korean fighter aircraft flew as close as 12 km (7 mi) to the border with South Korea, fired approximately 170 rounds of artillery shells toward the sea and test-fired a short-range ballistic missile that landed in the East Sea.
