Anti-government protesters have held their ground through a night of violent street clashes in the Ukrainian capital, despite police moving in to dismantle barricades erected in a street leading to government offices. Police attempted to move in on the protest camp early Tuesday, but faced fierce resistance from demonstrators who tossed fire bombs and stones in their direction. (AP Photo/Evgeny Feldman)
