From Kabul to Cambridge
There are more than 4,200 unaccompanied children seeking asylum in the UK, and the majority of them come from Afghanistan, according to British government figures.
Now the UK Border Agency has announced a plan to deport groups of teenage Afghan boys to a new four million pound reintegration centre in Kabul.
Ten years ago Mohammad Razai fled Afghanistan and arrived at the southern English port of Dover seeking asylum.
He was 15 years old, spoke no English, had a fake passport and just a bag of clothes.
Today he is a British citizen and is studying medicine at the prestigious Cambridge University.
This achievement is even more surprising considering the tragic circumstances of Mohammed's childhood in Kabul.
His family faced persecution for years because they belonged to the Hazara ethnic group. And when Mohammed was just a few months old, his father was arrested for involvement in anti-government activity and eventually executed during the Soviet occupation of Afghanistan.
Mohammed tells Outlook's Matthew Bannister his story.
