International Atomic Energy Agency (IAEA) Director Rafael Grossi stated on Friday that there is no evidence of any country conducting nuclear weapons tests.

U.S. President Donald Trump on Thursday directed the Pentagon to resume nuclear weapons testing “on an equal basis,” citing similar programs conducted by other countries.

North Korea is believed to possess as much as 2,000 kilograms of highly enriched uranium, reflecting its recent efforts to significantly expand its nuclear weapons program, South Korea’s Unification Minister Chung Dong-young said on Thursday.
