Interior Ministry members are on fire as they stand guard during clashes with anti-government protesters in Kiev, February 18, 2014. Several thousand protesters clashed with police near the Ukrainian parliament on Tuesday after being stopped from marching to the building in a move to keep up pressure on President Viktor Yanukovich. After being blocked by a line of trucks about 100 metres short of the building, protesters hurled stones at police, a Reuters witness said.
