After Russia invaded Ukraine last week, hundreds of innocent people have reportedly been killed and thousands more injured, displaced or left homeless.
Thousands more Ukrainian people, including young children, have been left with nothing: no shelter, clothing, food, school supplies or medication, and many of them have felt forced to flee the country in order to reach safety.
The United Nations' Refugee Agency has estimated that 660,000 refugees have now fled Ukraine. In a statement on social media on Tuesday, the Agency said: "~ 660,000 refugees have now fled Ukraine to neighbouring countries in the last six days.
