The United Nations said nuclear testing should never be permitted, giving a rare direct rebuke of the US after President Donald Trump ordered his administration to resume such tests after a 33-year moratorium.

“We shouldn’t forget the disastrous legacy of over 2,000 nuclear-weapons tests that have been carried out over the last 80 years,” UN spokesman Farhan Haq told reporters. He said the UN and Secretary-General Antonio Guterres believe “nuclear testing can never be permitted under any circumstances.”
