A change in the way that the war in Afghanistan is fought could be on the way.
The new commander of US-led forces in Afghanistan, Gen David Petraeus, is suggesting that he will review the rules of engagement.
Some troops have complained that the restraints, which curb the use of air power and heavy weapons if Afghan civilians are at risk, are putting Western forces in greater danger.
They also, it is claimed, make it harder to defeat the Taliban.
