The United Nations High Commissioner for Refugees (UNHCR) has reported that an estimated one million people have fled from Ukraine since Russia invaded. Christopher Boian, senior communications officer at UNHCR, joined Cheddar News to report on the current refugee crisis and what the world might expect if conditions continue to worsen. "We have planning figures that forecast as many as four million people could be forced to flee Ukraine," he said. "But that very much depends on how the conflict underway in that country at the moment unfolds in the days and possibly weeks ahead."
