Activity has been detected at North Korea’s main nuclear site, suggesting Pyongyang may be reprocessing radioactive material into bomb fuel since the collapse of a summit with Washington, a US monitor said on Wednesday.
The possible signs of fresh reprocessing activity last week come after a February summit between US President Donald Trump and North Korean leader Kim Jong Un ended abruptly without agreement on Pyongyang’s nuclear programme.
Since then North Korea has said it was mulling options for its diplomacy with the US and Kim said last week he was open to talks with Trump only if Washington came with the “proper attitude.”
The Center for Strategic and International Studies said satellite imagery of the Yongbyon nuclear site on April 12 showed five railcars near its uranium enrichment facility and radiochemistry laboratory.
“In the past these specialised railcars appear to have been associated with the movement of radioactive material or reprocessing campaigns,” the Washington-based monitor said.
“The current activity, along with their configurations, does not rule out their possible involvement in such activity, either before or after a reprocessing campaign.”
Trump and Kim held their first landmark summit in Singapore last June, where the North Korean leader signed a vaguely-worded deal on the “denuclearisation of the Korean peninsula.”
But their failure to reach agreement at their second summit in Hanoi on walking back Pyongyang’s nuclear programme in exchange for relaxation of sanctions has raised questions over the future of the wider process.
The US president walked away from a partial deal proposed by Kim, which included an offer to dismantle the Yongbyon complex.
About 100 kilometres (60 miles) north of Pyongyang, Yongbyon is home to the country’s first nuclear reactor, and is the only known source of plutonium for the North’s weapons programme.
Yongbyon is not believed to be the North’s only uranium enrichment facility and closing it down would not in and of itself signal an end to the country’s atomic programme.
North Korea suspended nuclear and missile testing during the diplomatic process in 2018 but the International Atomic Energy Agency has said there were indications that Yongbyon has been in use as recently as the end of February.
North Korea said on Thursday that it had test-fired a new type of "tactical guided weapon," its first such test in nearly half a year, and demanded that Washington remove Secretary of State Mike Pompeo from nuclear negotiations.
North Korea has criticised US National Security Adviser John Bolton’s “nonsense” call for Pyongyang to show that it’s serious about giving up its nuclear weapons, the second time it has criticised a leading US official in less than a week.
South Korean President Moon Jae-in will meet US President Donald Trump on Thursday hoping to help put denuclearization talks with North Korea back on track after a failed summit between the United States and North Korean leaders in February.
North Korean leader Kim Jong Un told Russian President Vladimir Putin peace and security on the Korean peninsula depended on the United States, warning that a state of hostility could easily return, North Korean media said on Friday.

South Korea is to invest 88 billion won ($74 million) to develop a weapons system by 2023 that can detect and strike drones, its procurement agency said on Tuesday, after incidents of infiltration by North Korean spy drones.
Prime Minister Boris Johnson’s government will seek to persuade Britain’s top court this week that his decision to suspend parliament until shortly before the date for Brexit was not illegal as Scottish judges concluded last week.
