An anonymous senior U.S. official said spy satellites had detected renewed activity at the North Korean factory that produced the country's first intercontinental ballistic missiles capable of reaching the United States.
The Post says new evidence, including satellite photographs, indicate the missiles are liquid-fueled intercontinental ballistic missiles and are being constructed at a factory that produced North Korea's first such missile capable of reaching the United States.
US President Donald Trump and North Korean leader Kim Jong-un met in Singapore on June 12 and signed an agreement in which North Korea committed to "complete denuclearisation of the Korean Peninsula" without specifying a timeline.

The findings, including satellite photos taken in recent weeks, indicated that the work was under way at the same factory that produced the country's first large ICBM, the Hwasong-15, in Sanumdong, on the outskirts of Pyongyang, according to the report.

The unified teams will mark the first time the two Koreas compete together in the Asian Games. Before we pull the plug on everything, let's see how the Trump administration handles this development.
The North Korean view, he says, is of "a distant future, when USA forces are completely withdrawn not necessarily from only the Korean Peninsula, but maybe from the entire East Asia, maybe from the Pacific and what about Hawaii, or what about surrender of US nukes and Russian nukes and Chinese nukes?" His North Korean counterpart, Lt. Gen. US intelligence agencies believe that it has been operational for at least a decade.
