North Korea increased production of enriched uranium for nuclear weapons at secret sites

North Korea has increased its production of enriched uranium for nuclear weapons at secret sites in recent months, contrary to Donald Trump’s claims that it was “no longer a nuclear threat”, according to a new report.

NBC News quoted more than a dozen US officials familiar with the intelligence assessments. Coming soon after satellite images showed rapid improvements being made to a North Korean nuclear research facility at Yongbyon, the developments will make it harder for Trump to claim that his summit with Kim Jong-un in Singapore this month was a success.

Neither of the concessions the US president claimed Kim had delivered – the destruction of a missile engine testing site, and the repatriation of the remains of US soldiers killed in the Korean war – has materialised so far.
