Four U.S. soldiers with NATO's International Security Assistance Force were killed in a roadside bombing in southern Afghanistan.
The coalition says the attack occurred Tuesday as the soldiers traveled with a convoy in the Zhari district of volatile Kandahar province.
In other violence, six civilians were killed in attacks in nearby Helmand province. In the first incident, a motorcycle bomber detonated his explosive at a market in the Garmser District killing at least three people and leaving nine injured. Elsewhere in the province three people were killed and four were wounded when a roadside bomb exploded in Marja district.
Meanwhile Tuesday, the Afghan Taliban says they have released the remaining four Turkish nationals held hostage since their helicopter went down in eastern Afghanistan last month. The aircraft had been traveling from Khost to the capital, Kabul, when bad weather forced it to make an emergency landing in the Taliban stronghold of Logar province on April 21.
The first four Turkish workers were freed on Sunday.
The militants are still holding the two pilots from Russia and Kyrgyzstan as well as the Afghan translator.
