South Korea informed for 3 North Korea patrol boats crossing the sea boarder between the two countries in the Yellow Sea. The Navy of South Korea fired warning shots against the North Korean vessels. The incident was reported at the boundary, named the Northern Limit Line (NLL), at around 4 p.m. local time (3 a.m. ET), yesterday.
The Navy of South Korea took measures and fired 10 warning shots. The North Korean patrol boats decided to return the fire. The Northern Limit Line (NLL) is considered as a maritime border which stretches from the western coast of the peninsula into the Yellow Sea. This is known as a boundary between the two neighbouring countries.
The boundary was set by the United Nations after the Korean War. North Korea does not respect the border and refuses to respect the decision of the UN.
There have been many incidents on and around the border between the two countries during the years. For example, on February 26, South Korean defense officials informed for a North Korean warship crossing into South Korean waters overnight.
The incident was reported in a moment when a joint exercise between the United States and South Korea was taking place. The Northern Limit Line is disputed by North Korea as a legitimate maritime border.
