"South Korea Plans Border Drills as North Korea Violates Buffer Zones"

South Korea has announced plans to conduct drills at the border with North Korea after claiming that the North's artillery drills have invalidated long-established buffer zones. This comes in response to North Korea's recent multiday bombardment of the border region with hundreds of artillery rounds, prompting South Korea to fire approximately 400 rounds in response. Tensions between the two countries have escalated, with the western sea border being the site of multiple skirmishes since the end of the Korean War.
