Quote:North Korean leader Kim Jong Un's half-brother was asked to serve as the leader of a North Korean government-in-exile before he was killed last week during a daring airport assassination, The Korean Times reported.

Kim Jong Nam reportedly turned down the offer, made by North Korean defectors in the U.S. and Europe, but Kim Jong Un may have still been unnerved about the proposition, according to The Korean Times.

A week since his Feb. 13 murder inside a Kuala Lumpur airport, the cause of Jong Nam's death remains a mystery. He may have been poisoned. Or it could have been nerve gas. Or ricin. Perhaps a particularly strong opioid.
