The South Korean navy fired on two North Korean vessels that had broached the enemy nations’ sea border on Friday.
According to a report in Reuters news agency, citing an official with the South Korean Joint Chiefs of Staff, the two Northern vessels were a fishing boat and a military patrol craft.
After South Korea fired warning shots around 7:30 a.m. Friday local time, the ships retreated north of the Northern Limit Line, an unspoken “border” in the Yellow Sea between the Korean peninsula and China.
There was no immediate indication of injuries or Northern retaliation.
The two Koreas have technically been at work for more than 60 years, as the 1953 deal that ended the Korean War was merely a cease-fire, not a peace treaty, and neither state accepts the legitimacy of the other.
