Kim Jong-un, leader of the DPRK lost some 20 kilograms.
"North Korean leader Kim Jong-un has lost around 20 kilograms after previously weighing about 140 kg, but he appears to have no health issues", Yonhap wrote citing the South Korean intelligence agency.
Since the stateman's health was often a matter of political speculations, the National Intelligence Service of North Korea ran a detailed test with the use of AI and other scientific methods. The tests showed that Kim Jong-un was completely healthy.
Last year, the media reported that Kim Jong-un might have undergone heart surgery, which left him in a grave condition for a while.
In August, the United Nations International Atomic Energy Agency announced that North Korea was restarting a nuclear reactor at a research center in Yongbyon, which became the basis for the country's nuclear program.
In the first week of September, North Korea successfully tested a new type of long-range cruise missiles.
And in the middle of the month, the authorities of South Korea and Japan recorded the launch of two ballistic missiles from North Korea, just a few days after the tests of cruise missiles in this country, probably with nuclear potential.
The two Koreas are in an arms race, and both are developing increasingly powerful missiles and other weapons.
However, North Korea's nuclear tests are causing international condemnation and concern. The United States has said North Korea's actions violate UN Security Council resolutions and pose a threat to the country's neighbors.
