North Korea appears to have begun dismantling part of a key rocket launch site in the country's north-west.
Satellite images of the Sohae station seen by US-based monitoring group 38 North suggest that Pyongyang is complying with the agreement reached between its leader Kim Jong-un and US President Donald Trump during their meeting in Singapore last month.
Both leaders had signed a deal to work towards complete denuclearisation
of the Korean Peninsula. But the deal was criticised for lacking details on when or how Pyongyang would renounce its nuclear weapons.
Mr Trump had said, the North Korean leader vowed to destroy an engine test site, but did specify which one.
Pyongyang has maintained that Sohae is a satellite launch site. But US officials suspect that it has been used to test ballistic missiles.
