KYIV, Ukraine — North Korean troops recently deployed to help Russia in its war with Ukraine have come under Ukrainian fire, a Kyiv official said Tuesday. It is the first time a Ukrainian official has said that Pyongyang’s units were struck, following a deployment that has given the war a new complexion as it approaches its 1,000-day milestone.
