FILE In this file photo taken on Thursday, Jan. 23, 2014, Protesters use a large slingshot to hurl rocks at police in central Kiev, Ukraine. Protesters in Kiev built the catapult to pelt firebombs at police at a longer distance and bigger damage. Thick black smoke from burning tires engulfed parts of downtown Kiev as an ultimatum issued by the opposition to the president to call early election or face street rage was set to expire with no sign of a compromise on Thursday.
