It is not the first time Penn has been in Ukraine, who was last in the country in late November.

At the time, photographs showed the star visiting the frontlines of the Ukrainian armed forces near the Donetsk region.

Penn has been involved in numerous international humanitarian and anti-war efforts over the years and founded the non-profit disaster relief organisation CORE in response to the 2010 earthquakes in Haiti, chronicled in the documentary Citizen Penn.

He also deployed teams to help with COVID-19 testing and vaccinations during the pandemic.

The documentary project he is working on is being produced by VICE Studios.
