North Korea 'vows to shut down nuclear test site'

South Korea says North Korean leader Kim Jong-un has promised to dismantle its nuclear test site next month.

The pledge was made during Kim's summit with President Moon Jae-in on Friday.

But there is no word about the future of North Korea's ballistic missile programme, or whether Pyongyang will agree to demands by US President Donald Trump, to get rid of its existing nuclear arsenal.
