Two North Korean vessels crossed the Northern Limit Line near Yeonpyeong-do Island in the
West Sea, at around 7:30 AM, Korea time this morning.
Seoul's Defense Ministry says... the patrol boat and fishing boat retreated northward
from the maritime border... after the South Korean Navy fired several warning shots.
The South Korean military has been put on alert given the heightened tension on the
peninsula. Officials say surveillance along the NLL has
been beefed up and the military is keeping a keen eye for any unusual activities north
of the border.
