North Korea has sent soldiers and millions of munitions, including missiles and rockets, to Russia over the past year, according to a new report by an international watchdog, which details the extent to which Pyongyang has helped Moscow “terrorize” Ukraine’s population over its three-year war.

International observers have called for further investigation and renewed diplomatic efforts to curb the illegal arms trade between Pyongyang and Moscow.

N Korea gave Russia over 100 ballistic missiles and as much as nine million rounds of ammunition, including artillery shells and rockets, for use in the war on Ukraine, an international watchdog said.
