According to United Nations estimates, more than 1.5 million Ukrainian have become refugees since Russia invaded. In cities still under bombardment, the situation is becoming a humanitarian catastrophe. During the second round of Russian-Ukrainian talks on March 3, the parties agreed to establish humanitarian corridors for the evacuation of civilians and the delivery of medicines and food. UN officials also say the war has killed at least 330 civilians and injured at least 675. These images are from the ninth day of the war.
