From the BBC:

Nato has said it needs to do better in its operations in Afghanistan, after coming under criticism from Afghan President Hamid Karzai.

Mr Karzai accused Nato and US-led troops of failing to co-ordinate with their Afghan allies, thereby causing civilian deaths.

A Nato spokesman said Mr Karzai had a right to be "disappointed and angry" over the scale of civilian casualties.

It came after a week in which up to 90 Afghan civilians were killed.

More civilians have been killed this year as a result of foreign military action than have been killed by insurgents, correspondents say.
