Australian Prime Minister Anthony Albanese said Wednesday Russia has reported Oscar Jenkins is alive and in custody. The Australian man went to Ukraine to fight against Russia's invasion and was feared dead.

On 14 January, Australia summoned Russian ambassador Alexey Pavlovsky to answer questions about Mr Jenkins’s status. “The Russian Federation is obligated to treat all prisoners of war in accordance with international humanitarian law,” a spokesperson said in a statement at the time.

The Australian government has been told by Moscow that one of its citizens in Russian captivity is still alive. Oscar Jenkins, a 32-year-old teacher, was captured last year while fighting for Ukraine.

Russia has lost about twice as many men to death and serious injury as Ukraine. But the trends favor the Kremlin.

The Ukraine conflict is the first major drone war in military history. Despite tactical losses on several parts along the line of contact, the Ukrainian military has continued to maintain strategic pressure on Russia by targeting and attacking major targets behind enemy lines.

A nuclear power plant was among the targets of a massive Ukrainian drone attack against Russian oil and power facilities, Russian officials and media outlets reported on Wednesday.
