Supporters of presidential candidate Viktor Yanukovich celebrate his victory in a presidential run-off vote during a rally in front of Ukraine's central electoral commission in Kiev, February 8, 2010. Ukrainian opposition leader Yanukovich claimed a slender victory in a presidential poll on Monday that could tilt the ex-Soviet state back towards Moscow, but bitter rival Yulia Tymoshenko had yet to concede defeat.
