How has life for children in Afghanistan changed in the past 10 years?
Under the Taliban, life was pretty grim. Everyday things like singing, whistling and flying a kite were against the law.
Even going to school was something only a small number were allowed to do. Girls were completely banned from getting an education 15 years ago.
Since the Taliban were overthrown in 2001, a lot has changed.
An extra 5.5 million kids are now going to school - a third of those are girls. But in many areas it's still hard to get an education.
Before the war, lots of people fled the country in fear of the old regime. But since the Taliban were defeated, more than 5 million Afghans have returned.
Whilst the lives of millions of people have improved, there's still a lot of work to do.
Afghanistan is the second poorest country in the world. One in four children die before they reach the age of five.
With fighting still going on, it's hard to say when Afghanistan will be able to offer a peaceful, stable future for its people.
