According to South Korea, North Korea launched two suspected ballistic missiles from an airfield. On Monday, video from a previous North Korean launch was shown on a television news broadcast.

North Korea conducted a test launch of two suspected short-range ballistic missiles off its east coast on Monday, according to South Korea’s military, marking the North’s fourth weapons launch of the month thus far.

The missiles were launched from Sunan airport, which is located on the fringes of Pyongyang’s northern outskirts, according to the South Korean military. It was not immediately possible to determine the exact time of the launch or the distance covered by the missiles.

The leadership of Kim Jong Un has recently declared that the country’s weapons activity is part of the country’s national defense and, as such, is a legitimate exercise of sovereign rights. Under resolutions of the United Nations Security Council, North Korea is prohibited from conducting such ballistic missile tests.

North Korea has been showing off new weaponry alongside its nuclear weapons and submarines, including anything from railway-launched missiles to hypersonic missiles.

According to North Korea’s state media, Mr. Kim, who has demonstrated a general disregard for international affairs in previous policy speeches, has reportedly urged authorities to increase the country’s “strategic military might.” This was the dictator’s first formal appearance at a weapons test in two years, and he made the statements last week.

The other tests, which took place in recent days, comprised two Ballistic Missiles fired from a train vehicle as well as what Pyongyang says is hypersonic technology, according to the North.

Mr. Kim has urged self-reliance and warned of food shortages during the epidemic, which has caused North Korea to draw home throughout the crisis. In more than two years, North Korea has not engaged in official disarmament discussions with the United States.
