North Korea has criticized UN Secretary-General over his remarks in support of Pyongyang’s complete denuclearization.

The US may try to use the persisting security crisis in Ukraine as a pretext to deploy armaments -- including nuclear weapons -- in space, Russia’s deputy UN envoy has warned.

Iran's UN ambassador says US failure to give assurance about Tehran’s enjoyment of full economic benefits of the 2015 deal is the main obstacle to its revival.

Russia has dismissed the "utterly unfounded" speculations that it may use nuclear weapons in Ukraine, saying it would only use its nuclear arsenal in response to "direct aggression" by NATO countries over the ongoing conflict in the former Soviet state.

North Korean leader Kim Jong-un has wrapped up a key meeting with top military officials, ordering the country's defense capabilities to be strengthened. 

The global nuclear arsenal is expected to grow in the coming years for the first time since the Cold War while the risk of such weapons being used is the greatest it has been in decades.

North Korea has claimed “good results” in the fight against the country’s first confirmed coronavirus outbreak even as the number of people with fever symptoms crossed two million.

The US is set to ramp up weapons delivery to Ukraine, deepening its involvement in the simmering war in defiance of repeated warnings by arch-foe Russia.

North Korean leader Kim Jong-un has once again warned that his country would preemptively use nuclear weapons if threatened.
