From the BBC:

Figures from the Office of the UN High Commissioner for Human Rights show a sharp increase in the number of civilian casualties in Afghanistan.

They show that August had the highest number of deaths since the overthrow of the Taleban almost seven years ago.

The figures, released in Geneva, follow the killing of two World Health Organisation doctors in Afghanistan.

The UN says that from January to August 1,445 civilians were killed - a rise of 39% on the same period last year.
