When a video of a Russian soldier captured in Ukraine denouncing the invasion went viral, it wasn’t long before observers pointed out that such footage, if produced by a government, might well violate the Geneva Conventions.

Detainees “must be treated with dignity, and not exposed to public curiosity — like circulating images on social media,” the ICRC said as part of a Twitter thread explaining those rules.

Some Ukraine supporters abroad cheered images showing Ukrainian teens suiting up for war in their skateboarding gear.

Others raised questions about how such photos would be received had they come from other parts of the world.
