There are grave concerns for Australian man Oscar Jenkins after reports of his death in Ukraine.

The former Melbourne teacher travelled to Ukraine to fight Moscow’s invasion and became the first known Australian to be captured in the conflict last year, when footage emerged of the 32-year-old being questioned and hit by Russian soldiers.

Following unverified reports of Jenkins’ death, a Department of Foreign Affairs and Trade (DFAT) spokesperson said Australian officials continue to have grave concerns for his welfare.

“The Australian government is making urgent enquiries following reports of Oscar Jenkins’ death,” the spokesperson said.

“These reports have not been verified, but we continue to have grave concerns for Mr Jenkins’ welfare.

”At the foreign minister’s direction, the Russian ambassador was called into DFAT on January 13 to seek information and reiterate Australia’s expectations that Russia will comply with its obligations under international law.

“The Russian Federation is obligated to treat all prisoners of war in accordance with international humanitarian law.

“DFAT is continuing to provide consular support to Mr Jenkins’ family during this difficult time.

“His family has requested privacy and we ask that media respect their wishes.”
