More than 600 children with cancer have been evacuated from Ukraine in order to resume life-saving treatment in Europe and North America.
Doctors on the ground say more than 2,000 children with cancer may still need help to leave Ukraine. Some can't leave because they are just too seriously ill. Those who can, need urgent treatment.
Iryna and her family, who are staying the Carpathian monastery in north-east Romania after fleeing from Kharkiv, said they have settled into life there.
