The firing came shortly after South Korea ended five-day naval drills off the west coast that the North called a rehearsal for an invasion, vowing to retaliate.
All the artillery shells harmlessly landed into the North’s waters and caused no damage to the South, a South Korean Joint Chief of Staff officer said on condition of anonymity, citing department policy.
South Korea considered the firing to be part of a military drill by North Korea but still bolstered its military readiness against further provocation, the officer said. The South also warned Pyongyang over the firing by naval radio, he said.
“This was their way of saying ‘We’ll respond to military drills with military drills,'” said Yang Moo-jin, a professor at Seoul’s University of North Korean studies.
