Policemen rest as they guard the Ukrainian parliamnet in Kiev on February 20, 2014. Ukraine's brittle truce shattered on Thursday in fierce clashes between baton-wielding protesters and riot police that claimed at least 27 lives just as EU envoys were holding crisis talks with the embattled president. Bodies of anti-government demonstrators lay amid smouldering debris after masked protesters hurling Molotov cocktails and stones forced gun-toting police from Kiev's Independence Square -- the epicentre of the ex-Soviet country's three-month-old crisis.

Ukraine's embattled leader announced a "truce" with the opposition as he prepared to get grilled by visiting EU diplomats over clashes that killed 26 and left the government facing diplomatic isolation. The shocking scale of the violence three months into the crisis brought expressions of grave concern from the West and condemnation of an "attempted coup" by the Kremlin. AFP PHOTO/BULENT KILIC
