North Korea may be preparing for a missile or space launch, US news outlet NPR has reported, based on satellite image analysis of a key facility near Pyongyang. NPR said the images of Sanumdong, one of the facilities Pyongyang has used to produce inter-continental ballistic missiles and space rockets, were taken days before US President Donald Trump and North Korean leader Kim Jong Un met in Hanoi for their high-stakes summit, which ended in failure.

The photos by DigitalGlobe show the presence of cars and trucks at the site on February 22, said NPR, which has exclusive access to the imagery. It added that rail cars and cranes can also be seen at a yard. The Sanumdong analysis comes days after the specialised website 38 North and the Center for Strategic and International Studies said Pyongyang may have resumed operations at its long-range rocket launch site at Sohae, based on their study of satellite imagery from March 6.
