Kim Jong Un has reportedly hired ex-KGB bodyguards to defend him against a US assassination
Japan's Asahi Shinbum reported that Kim hired about 10 former KGB counterterrorism agents to train his bodyguards on how to detect and respond to terrorist attacks.
The KGB, the former Soviet Union's main security and spy agency, had decades of practice in defending high-value targets against attempts at regime change.
The source told Asahi Shinbum that Kim was particularly scared of US advanced-weapons systems, like the Gray Eagle drone the US is set to operate in South Korea in 2018.
However, it's unclear how counterterrorism bodyguards could protect Kim against a drone high in the sky raining down bombs.
South Korean media has reported that the US and South Korea have been working together on a "decapitation force" to kill the North Korean leader in the event that Pyongyang becomes intolerably aggressive.
Kim has a history of going to extreme measures to shore up his reign over North Korea, with some reports saying he killed his half-brother Kim Jong Nam to thwart a Chinese-backed coup attempt.
