Warning shots fired at inter-Korean border as military tensions flare
- North Korea said its artillery launches on Monday were in response to the South firing at a merchant ship off the peninsula’s west coast
- Their poorly marked sea boundary is a source of long-running skirmishes and violence, including two attacks in 2010 that killed 50 people

North Korea’s military said its coastal defence units responded by firing 10 rounds of artillery warning shots towards its territorial waters, where “naval enemy movement was detected”. It accused a South Korean naval ship of intruding into North Korean waters on the pretext of cracking down on an unidentified ship.

There were no reports of fighting, but the sea boundary off the Korean peninsula’s west coast is a source of long-running animosities.
The American-led UN command drew a boundary at the end of the 1950-53 Korean war, but North Korea insists upon a boundary that encroaches deeply into waters controlled by the South.
Among the deadly events that have happened in the area are the North’s shelling of a South Korean island and its alleged torpedoing of a South Korean navy ship, both in 2010. The two attacks killed 50 South Koreans.
Cheong Seong-chang, a senior analyst at the Sejong Institute think tank, said it was unimaginable for a North Korean merchant vessel to have crossed the de facto maritime border between the two rivals without being instructed to do so.
