Kim Jong Un, North Korea's supreme leader, is said to have put an entire city under lockdown after 653 bullets disappeared during a military retreat.

According to two people who spoke to Radio Free Asia, the dictator's officials have gone door-to-door in the city of Hyesan, which has a population of around 200,000 people, searching for ammunition.

Residents of Ryanggang, where Hyesan is located, have confirmed that the city will remain in lockdown until all the bullets have been found. The missing ammunition reportedly disappeared on March 7 during a military withdrawal between February 25 and March 10.

According to sources, during the evacuation, soldiers discovered they had misplaced the bullets and tried to locate them before informing authorities. When it became clear that they couldn't find the bullets, the authorities were informed, resulting in a city-wide lockdown.
