North Korean leader Kim Jong-un has died in a car crash, state news agency KCNA said.
The 73-year-old Kim Yang-gon was a secretary of the ruling Workers’ Party and was in charge of ties with South Korea.
He was part of a high-level delegation from North Korea that helped ease a stand-off with the South in August, after an exchange of artillery fire.
The state news agency called him Kim Jong-un’s “closest comrade and a solid revolutionary partner”.
“Comrade Kim Yang-gon, a Workers’ Party secretary and member of the party Central Committee Politbureau… died in a traffic accident at 6:15am, Tuesday, at age 73,” KCNA said, without giving details.
It added that Kim Jong-un would lead an 80-member state funeral for Mr Kim on Thursday.
