Nearly one in four of Ukraine's 44 million people has been forced to flee since Russia began its invasion war in the country just over three weeks ago, according to the UN.
3.2 million Ukrainians have fled to neighboring EU countries.
Even within the country's borders, millions of people are on the run.
According to OCHA, the UN Office for the Coordination of Humanitarian Aid, 6.5 million Ukrainians are fleeing the country.
Children with disabilities are at risk of being left behind
Sky News reports on several homeless people after shelling a residential building in the Podil district of Kyiv on Saturday morning, where at least one person was found dead.
It is just one of all residential buildings that have been bombed in the country in recent weeks and forced people to leave their homes.
Escape the country is not possible for everyone.
For many seniors, it becomes a difficulty without the help of relatives.
Save the Children also alerts children at orphanages and institutions that are at risk of being left behind when relatives flee, children with disabilities are particularly vulnerable.
Many children are also at risk of falling victim to traffic jams.
Twelve million stuck in war zones
According to the UN refugee agency UNHCR, this is the worst refugee crisis in Europe since World War II.
In addition to the nearly ten million who are on the run, more than twelve million Ukrainians are also trapped in war zones from which they can not recover due to the great risks and the extensive destruction of bridges, roads and lack of information.
