A Chinese Boeing 747-4J6 private jet is flying to Singapore after taking off from an airport in Pyongyang, North Korea's capital, South Korea's Yonhap News Agency reported on Sunday, citing a flight route-tracking website (https://www.flightradar24.com/CCA061/11ac2ef5).

The takeoff of an Air China plane was detected at 8:30 a.m., according to Flightradar24.

One hour later, Kim's private jet also took off from Pyongyang for Singapore.

The North Korean leader and his entourage are on one or the other of the flights. The two planes are travelling in Chinese airspace, apparently for security reasons.

While the real-time location of the Chinese jet can be traced with the website, Kim's private jet "Chammae 1" is untraceable because its code name is confidential.
