South Korea Fires on North Korean Patrol Boat After Sea Border Crossing

South Korea fired warning shots at a North Korean vessel that crossed the maritime border.
The incident came amid recent tension over North Korea's missile tests.
The South's Joint Chiefs of Staff fired warning shots and broadcast warnings to expel the North Korean patrol boat that breached the Northern Limit Line.
A South Korean patrol ship came into "minor contact" with a nearby Chinese fishing vessel due to bad visibility, resulting in no safety issues but slight injuries among the South Korean crew.
North Korea has disputed the NLL since the 1990s, arguing it should lie far to the south.
