SLAVIANSK/DONETSK, Ukraine (Reuters) - Ukraine's acting president accused Russia of aiding "terrorists" who killed a politician from his own party, urging a crackdown in the east on Tuesday that could hamper international efforts to defuse the crisis.
As Vice President Joe Biden flew home from a brief visit to demonstrate solidarity with Kiev's new leaders against Moscow, Oleksander Turchinov called on security forces to relaunch an operation against pro-Russian separatists that was suspended after a deal with Moscow last week on disarming militants.
