The United States said for the first time on Wednesday, October 23, that it had seen evidence of North Korean troops in Russia.
The United States has assessed that at least 3,000 North Korean troops were transported by ship to the eastern Russian city of Vladivostok in early-to-mid October.
The Kremlin has previously dismissed Seoul's claims about the North's troop deployment as "fake news" and a North Korean representative to the United Nations in New York called it "groundless rumors" at a meeting on Monday.
Both Moscow and Pyongyang have also denied weapons transfers, but they have pledged to boost military ties and signed a mutual defense treaty at a summit in June.
