Australia is working to verify the authenticity of a video that purportedly shows one of its nationals captured by Russian forces while fighting in Ukraine.

The video, posted to Russian Telegram accounts, shows a man with a muddied face being questioned in a forested area by another man speaking Russian, who appears to hit him twice across the head.

The man, whose hands appear to be tightly bound with silver tape, identifies himself on camera as 32-year-old Oscar Jenkins and says he lives in Australia and Ukraine.

When asked about the reports of a Melbourne man captured by Russia, Australian Prime Minister Anthony Albanese told reporters Monday the government was seeking information through the Australian embassy in Moscow.

“This is concerning news, and we’re working through the Department of Foreign Affairs and Trade (DFAT) to provide support, including, for this gentleman, trying to ascertain the details and the facts which are there,” Albanese said.

“We know that the Russians often put out information that isn’t right,” he added. CNN has reached out to DFAT for further comment.
