South Korea on Saturday fired warning shots at a patrol boat from the Democratic People's Republic of Korea (DPRK), Yonhap news agency reported on Sunday, citing military officials.
The DPRK military ship sailed south several hundred meters away from the northern limited line (NLL) when it was clamping down on fishing boats at about 3:30 p.m. local time on Saturday, according to the South Korean military.
South Korea's navy vessels fired five warning shots with 40-mm machine gun at the DPRK boat, which return back minutes after the firing.
There was no more clash between the two sides, a military official was quoted as saying by Yonhap.
