KYIV (Reuters) - Fatigue among donors could compound the issues created by the mass displacement of Ukrainians after Russia's invasion, making the problem more expensive to deal with in the long run, the U.N. migration agency chief said in Kyiv on Thursday.

Russia's full-scale invasion of Ukraine in February 2022 triggered the biggest refugee crisis in Europe this century, with 6.5 million Ukrainian refugees having been recorded globally and 3.7 million displaced within Ukraine, according to U.N. data.
