From the BBC:

Education Minister Mohammad Hanif Atmar said the answer lay in what he called the "Afghanisation" of security.

Mr Atmar, who is a close ally of President Hamid Karzai, said Afghan forces needed more training.

In the latest violence, officials say the Taleban killed six people in the western province of Herat.

Traditional system

While Nato leaders have been calling for member countries to commit more troops to Afghanistan, Mr Atmar told the BBC that this was not the answer.

He says a traditional Afghan system, with local communities being allowed to practice self-defence, would be more effective.

He believes that Afghan forces could defeat the Taleban in five years, instead of the 15 he believes Nato would need.
