Russia recently used short-range ballistic missiles (SRBMs) sourced from North Korea to conduct multiple strikes against Ukraine, the White House said on Thursday, citing newly declassified intelligence, Reuters reports.
National security spokesperson John Kirby told reporters the United States will raise the development with the United Nations Security Council.
Kirby called North Korea's arms transfer to Russia a "significant and concerning escalation" and said the United States would impose additional sanctions against those facilitating the arms deals.
Both Moscow and Pyongyang have denied conducting any arms deals, but vowed last year to deepen military relations.
The use of the missiles drew condemnation from Britain, as well as South Korea, which had reported in November that North Korea may have supplied SRBMs to Russia as part of a larger arms deal that also included anti-tank and anti-air missiles, artillery and mortar shells, and rifles.
"Our information indicates that the Democratic People's Republic of Korea recently provided Russia with ballistic missile launchers and several ballistic missiles," said Kirby, using the official name of North Korea.
