17 Photos From Ukraine That Are Absolutely Unbelievable

AP/Efrem LukatskyRiot police clash with anti-government protesters outside Ukraine's parliament in Kiev, Ukraine, Tuesday, Feb. 18, 2014.

Anti-government protests in Ukraine reached their most violent point on Tuesday, with at least 18 people killed and hundreds injured following violent clashes between police and opposition activists.

There's little sign the protests - which have been ongoing since December - will end any time soon, but it's hard to imagine seeing such jarring images continuing to emerge from the streets of Kiev.

From riot police using ancient military tactics to defend against attack to streets quite literally engulfed in flames, the photos coming out are totally insane.

Reuters photographers have been documenting the protests, and we've picked out the ones that show how crazy it really is on the ground.
