North Korea says it will be conducting live fire drills near its de facto maritime border with the South today.
The regime sent a notice to South Korea through the truce village of Panmunjom this morning.
In response, the South Korean military has ordered fishing vessels to leave the area in the West Sea and notified residents of nearby border islands to be prepared.
The South Korean military says if any shells from the firing drills fall south of the Northern Limit Line, it will respond with force.
North Korea conducted a similar drill last month, which resulted in the two Koreas exchanging fire across the maritime border after more than 100 rounds from North Korea landed south of the border.
