The South Korean military responded

to North Korean shells that fell into the sea on the southern side of

the Northern Limit Line (NLL) during Chosun People’s Army military

exercises Monday.

North Korea declared a no-fly, no-sail zone in the West Sea

[Yellow Sea] this morning, prior to the beginning of the exercises. The exercises then began at 12:15pm, according to South Korea’s Joint Chiefs-of-Staff.

At 12:40pm, residents of two local islands (Yeonpyeong and Baekryeong) were ordered to move to shelters.

Update: The South Korean government revealed later this afternoon that the two Koreas traded hundreds of shells during today’s exchange of fire. This article has been updated to reflect that fact.
