The commander of US and Nato forces in Afghanistan has delivered his long-awaited assessment of the war to his bosses in Brussels and the Pentagon.

General Stanley McChrystal says success can be achieved, but with a revised strategy.

The call for change comes as US forces continue to suffer casualties, with August being the bloodiest month for them since the military operation began eight years ago.

The contents of McChrystal's report will remain confidential, but it is widely understood he wants to bolster local Afghan forces, shifting the focus from fighting the Taliban to protecting civilians.

Al Jazeera's James Bays reports from the capital, Kabul, and discusses McChrystal's idea with Mir Ahmed Joyanda, and independent member of the Afghan parliament.
