North Korean leader's half-brother 'was a CIA informant'

North Korean leader Kim Jong-Un's deceased half brother Kim Jong-Nam was working as a spy for American intelligence.

That's according to a report in The Wall Street Journal, which said he was killed in 2017 while on a trip to meet his Central Intelligence Agency (CIA) contact.

The Journal cited a person familiar with the matter, adding that Kim Jong-Nam had met with CIA operatives earlier and established a "nexus".

In fact, a Japanese news outlet had reported in 2017 that Kim Jong-Nam had met with a US intelligence agent in a hotel in Malaysia, days before being killed at the Kuala Lumpur International Airport.
