North Korea fired 100 artillery rounds into a maritime "buffer zone" Wednesday, Seoul's military said, hours after Pyongyang launched a series of missile tests including one that landed near South Korean waters.
"North Korea fired around 100 artillery rounds from the Kosong area in Kangwon into the 'buffer zone' north of the Northern Limit Line," Seoul's Joint Chiefs of Staff said, referring to the maritime border between the two Koreas.
Earlier, the military said it was the "first time since the peninsula was divided" at the end of Korean War hostilities in 1953 that a North Korean missile had landed so close to the South's territorial waters.
"President Yoon pointed out today that North Korea's provocation is an effective territorial invasion by a missile that crossed the Northern Limit Line for the first time since the division," his office said in a statement.
The missile closest to South Korea landed in waters just 57 kilometers east of the mainland, the military said.
Pyongyang's latest test-firing came as Seoul and Washington staged their largest-ever joint air drills, dubbed "Vigilant Storm", which involve hundreds of warplanes from both sides.
