A multitude of videos circulating the Internet show the outrageous levels of violence in the Ukrainian capital. In one video from Radio Svoboda, Radio Free Europe's Russian service, a riot policeman with an unmistakable AK-47 assault rifle fires off the screen.
The video then cuts to footage of a sniper in the prone position, flanked by other police. Eventually, they all scamper out of frame.
In a Sky News video, another riot police officer fires his AK-47 as he retreats down a street.
It's unclear what he's firing at, though the news anchor suggests some sort of "firework" went off above the police.
