Both North and South Korean officials revealed they exchanged warning shots along their disputed western sea boundary on Monday, 24 October. Kim Jun-rak, a spokesperson for South Korea's Joint Chiefs of Staff, said the country's navy fired shots to repel a North Korean merchant ship they say violated the sea boundary. North Korea’s military said it fired 10 rounds of artillery shells back as a warning to South Korea."We urge North Korea to stop its continued provocations and absurd claims to undermine peace and stability on the Korean peninsula," Mr Jun-rak said.
