S.Korea fires missiles in response to North's own

STORY: South's President Yoon Suk-yeol described as "territorial encroachment."

It was the first time a ballistic missile had landed near the South's waters since the peninsula was divided in 1945, and the most missiles fired by the North in a single day. South Korea issued rare air raid warnings and launched its own missiles in response.

The missile landed outside South Korea's territorial waters, but south of the Northern Limit Line (NLL), a disputed inter-Korean maritime border.
