From the BBC:
President Hamid Karzai [of Afghanistan] cried last month as he spoke of his inability to stop militant attacks and coalition forces “killing our children”.
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.
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.
