There are fears for the welfare of an Australian man reportedly captured by Russian soldiers while fighting with Ukrainian forces in the Donbas region.

In videos circulated on social media, the visibly bruised and shaken man identifies himself as Oscar Jenkins, 32, as he is interrogated and beaten by his Russian-speaking captor.
