MEDYKA, Poland/SIGHETU MARMATIEI, Romania (Reuters) - A growing tide of Ukrainian refugees fleeing a brutal Russian invasion streamed into central Europe on Thursday, as volunteers and officials speeded up efforts to process arrivals whose numbers a U.N. official said had crossed the one million mark.

With Russian forces intent on advancing towards Kyiv and bombing some other Ukrainian cities into wastelands, the U.N. refugee agency also said the conflict looked set to trigger Europe's largest refugee crisis this century.
