Video has emerged that appears to show missing Australian Oscar Jenkins alive and seemingly in Russian captivity.

The unverified footage shows the prisoner of war confirming that reports about his execution were incorrect.

It was posted to YouTube about a week ago, but has not been verified.

“My name is Oscar Jenkins, I’m Australian,” he says to the camera.

The person filming states the date is January 17 and can be heard asking Jenkins questions.

“You are alive, so the information about your death is not right?” says the man.

“Correct,” Jenkins responds.

The man says Jenkins is a prisoner of war captured from Ukraine’s army, the 66th Mechanised Brigade.

“Tell us about your health condition, about your mood. Are you OK?” the man asks the Australian.

“I would like more freedom,” Jenkins responds.

“I feel a bit weak. I’ve lost a lot of weight. I have a broken arm still, I think, and my hand is not good.”

The man ends the video stating: “Everything is okay. He is alive and I think he will [be] better.”

Last month, Russia revealed that Jenkins was alive, following grave fears that the former teacher had been executed.

Russia’s ambassador to Australia told officials Jenkins was detained by Russian Armed Forces while fighting for Ukraine, but was alive.

Foreign Minister Penny Wong said Australia had received the update, but serious concerns remained for Jenkins’ welfare.

The Albanese government has called on Russia to treat the prisoner of war justly and release him.

In January, Russian ambassador Aleksey Pavlovsky advised officials Jenkins was in custody on Russian territory and his health condition was “normal”.

Australia is working with Ukraine and the Red Cross to access Jenkins and independently verify his welfare.

He is the first Australian combatant reportedly captured by Russian forces and his death would have marked the first for an Australian prisoner of war in more than 70 years.

In a social media video circulated in December, Jenkins was shown speaking a mix of broken Russian and English.
