The photos, provided to the Organization for Security and Co-operation in Europe, appeared to show the same man taking part in operations in Kramatorsk and Sloviansk in eastern Ukraine, and in operations in Georgia in 2008.
Another group of photos appeared to link a gunman seen in photos in Kramatorsk and Sloviansk to a team in the Russian special forces.
Ukraine's permanent representative to the International Organizations in Vienna said the photos provided "growing evidence of Russia's involvement in instigating and co-ordinating the separatist actions that destabilise the situation in the east of Ukraine".
Можно безнаказанно и сколь угодно долго врать одному человеку. Можно не слишком долго и не слишком бесстыдно врать многим людям сразу. Но нельзя бесконечно долго и абсолютно бесстыдно врать целому народу.
