A Ukrainian war journalist who has worked for several local and international media outlets has been missing for over a week, according to his friends, colleagues and multiple Ukrainian publications.

Maks Levin is a photojournalist and documentary filmmaker who disappeared while working on the front lines near Kyiv, his friend and colleague Markiian Lyseiko said on Tuesday . On March 13, Levin apparently drove in his own car to photograph the fighting in the Vyshhorod district an area facing intense Russian violence.

The journalist reportedly left his car near the village of Guta-Mezhigirska and went south toward the village of Moschchun. His last communication was apparently from that morning, after which his phone went offline. Levin may have been injured or captured by Russian troops, Lyseiko said.

Me, I will stay on the front line as long as I am physically able, Levin told VICE in an interview published on March 9. These soldiers are my friends.
