As Britain gets ready to send its troops into Afghanistan, Mohammed Humayun is already involved in the campaign.

Rebel soldiers

He took over the role as leader of the group of rebel soldiers when his father died three months ago. He was killed in a Taleban rocket attack.

Mohammed owns six tanks and his prize possession is a rocket launcher which can fire three-metre long missiles.

Mountains

The army he commands is one of many small groups of fighters based in the mountains of Afghanistan, who are trying to topple the ruling Taleban.

And he does not see what is wrong with being a soldier at such a young age.

Already married

He said: "Children make great soldiers. They are strong and fast and they are very brave."

Muhammed is already married to 13-year-old Jamila and, unlike his father who had three wives, he plans to stick to just one.

Ambition

Muhammed lives with his wife and mother, and his father's other wives, near the town of Kalafgan. He also has a string of bodyguards who carry machine guns.
