A United Nations report says Afghanistan passed a grim milestone with more than 100,000 civilians killed or hurt in the last 10 years since the international body began documenting casualties in a war that has raged for 18 years.

The United States envoy who is negotiating with the Taliban to end the war in Afghanistan says the peace process needs to be accelerated in the wake of a deadly attack on a wedding in the capital, which was claimed by the local ISIS affiliate.
