The North Korean leader, Kim Jong-Un has ordered his military men to prepare enter "a wartime state" after an exchange of fire with South Korea. He had told the soldiers to prepare for war from 5pm local time after the two countries exchanged gunfire at the fortified border. North Korea fired 2 shells , and South Korean fired dozens of shells in response.
The tension of war started after 2 soldiers were seriously wounded on August 4. South Korea accused the North of deliberately planting the land mines, an allegation Pyongyang denied. South Korea isn't accepting the denial started what both countries had agreed to stop doing for more than a decade.
North and South Korea started the use of loudspeakers to broadcast propaganda since the early 1990s, but the 2 sides agreed to stop their use in 2004. All was ok, until South Korea started using it again to broadcast propaganda against the North due to the land mines they accused North Korea of planting
North Korea then gave an ultimatum of 48 hours or South Korea might face military action, and since the loudspeaker won't stop, North Korea said the action of South Korea is a "a direct action of declaring a war"
According to CNN, a U.S official said that the United States believed North Korea fired the South Korea loudspeaker on Thursday.
North Korea also started its own propaganda over the border, the same day the South Korea army started Military exercises with the United states and other countries, and Pyongyang sees this as a prelude to an invasion.
Responding to the threat, a South Korean defence ministry in a statement, Our military has stepped up monitoring and is closely watching North Korean military movements
