The big one -- the only one, in NATO's eyes -- is the killing of civilians by ISAF forces.

An excerpt from the BBC story:

A spokesman for the Nato-led force, said efforts were under way to reduce civilian deaths in military operations.

But he said Nato had killed far fewer people last year than the Taleban, who launched more than 100 suicide attacks.

President Hamid Karzai cried last month as he spoke of his inability to stop militant attacks and coalition forces "killing our children".

I believe the single thing that we have done wrong... is killing innocent civilians Richard Nugee Nato spokesman

He has come under growing pressure over civilian deaths as violence has raged across the south and east. Bloodshed in Afghanistan last year returned to levels not seen since the fall of the Taleban in 2001.

The BBC's Dan Isaacs in Kabul says, according to Nato, there is to be a greater emphasis on the strategic targeting of the Taleban leadership.

He says the extent of the civilian deaths, often in air strikes on local communities believed to be harbouring Taleban fighters, has brought much criticism of Nato both from within and outside Afghanistan.

Nato forces in Afghanistan are accused of killing civilians in a number of air strikes and gun battles during operations against the Taleban and their allies.

In one incident in Kandahar province in October, 20 members of one family were among villagers killed by Nato bombing, Afghan officials said. ...

The authorities say about 4,000 people died last year in attacks by the Taleban and their allies and in raids by Nato-led troops - about a quarter of them civilians.
