According to the US intelligence agencies, North Korea is renovating a factory that was used to build the government's first intercontinental ballistic missiles, The Washington Post said Monday, citing unnamed officials familiar with the information.
The evidence suggests that North Korea is working on at least one, possibly two, liquid-fueled ICBMs at a research facility near Pyongyang, the report added.
However, US media reported earlier in July that Pyongyang was continuing to develop its nuclear arsenal, trying to deceive the United States about its denuclearization efforts.
In June, CBS News reported that Pyongyang had agreed to destroy a test site that was used to develop an intercontinental ballistic missile capable of hitting the US mainland: The so-called Sohae Satellite Launching Ground in the North Pyongan province, which is believed to be where the Hwasong-15 long-range missile was tested.
North Korea made rapid progress in nuclear research last year, conducting its strongest atomic test to date and testing a series of missiles. On June 12, North Korean leader Kim Jong Un met with US President Donald Trump in Singapore, where the two leaders issued an agreement that requires Pyongyang to denuclearize in exchange for a freeze of the US-South Korean military drills and eventual sanctions relief.
