A priest stands on February 21, 2014 in the ruins of Kiev's Trade Union building. Ukraine's parliament on February 21 voted to return the ex-Soviet country to its 2004 constitution, which limits the president's powers and gives lawmakers the right to appoint key ministers. The constitutional change was supported by 386 deputies in the 450-seat Verkhovna Rada shortly after President Viktor Yanukovych and top opposition leaders signed a deal to end the country's three-month political crisis.

Bodies of anti-government demonstrators lay amid smouldering debris after masked protesters hurling Molotov cocktails and stones forced police from Kiev's iconic Independence Square -- the epicentre of the ex-Soviet country's three-month-old crisis.
