North Korea 'to close nuclear site' in May and open facility to US and Seoul

North Korean leader Kim Jong Un has vowed to shut down the country's nuclear test site in May and open the process to experts and journalists from South Korea and the United States, Seoul's presidential office has said.

The event may serve as a dramatic set-up to Mr Kim's crucial nuclear negotiations with President Donald Trump that may take place in the next few weeks amid widespread scepticism on whether the North will ever fully surrender its nuclear weapons.
