A protester  throws  a stone towards a burning police bus in front of him, during clashes with police,  in central Kiev, Ukraine, Sunday, Jan. 19, 2014. Hundreds of protesters on Sunday clashed with riot police in the center of the Ukrainian capital, after the passage of harsh anti-protest legislation last week seen as part of attempts to quash anti-government demonstrations.
