The situation in eastern Ukraine can best be described as chaotic. While it’s clear there is violence occurring between pro-Russian groups and pro-Ukrainians (who desire closer ties to Europe), not much else is clear. Photos and video from the region show streets filled with a volatile mix of protesters, police, armed soldiers, civilians, and militia, wearing widely varying uniforms (or just street clothes). Many are masked, their exact motives and backers unknown as they attack their opposition, or raid government buildings, and tear down each others’ flags. Some appear to be more at play than at war, but the stakes are deadly. Dozens have been killed in just the past week alone in gun battles, fires, and beatings — even a Ukrainian military helicopter was shot down yesterday. Gathered here are images of the chaos in Ukraine from the past week, as fears grow that violence will escalate even further.
