People, mostly women, and children, were fleeing the frontline towns of Bucha and Irpin after heavy fighting broke out between Ukrainian and Russian forces in recent days. Since Russia invaded Ukraine one month ago on 24 February 2022, more than three million Ukrainians became refugees, around 700 civilians were killed and over 1.000 more injured, the United Nations said.
