US intelligence officials have determined that Russia has acquired ballistic missiles from North Korea and is seeking close-range ballistic missiles from Iran as Moscow struggles to replenish supplies for its war with Ukraine, the White House said on Thursday.

Recently declassified intelligence found that North Korea has provided Russia with ballistic missile launchers and several ballistic missiles, National Security Council spokesman John Kirby said. Russian forces fired at least one of those ballistic missiles into Ukraine on December 30 and it landed in an open field in the Zaporizhzhia region, he said.
