As Dancewater noted in the comments yesterday, the UN reports that Afghan civilian casualties rose 22% last year from the year before, with 3,699 civilians killed and 6,849 injured. This is the highest number since the UN started keeping track in 2009. (One wonders why it took them so long to get around to it.) Most are killed as bystanders in ground engagements, rather than by explosive devices, due to indiscriminate use of rockets and mortars. The report blames the majority of civilian casualties on insurgents.
