Six American soldiers died in a crash involving an aircraft in Zabul, southern Afghanistan, on Tuesday afternoon.
The International Security Assistance Force (Isaf) said the cause of the crash is unknown, but an investigation has been launched into the incident.
The Taliban claimed they killed the soldiers and wrote on Twitter that they had shot down the helicopter in the province bordering Helmand and Pakistan.
Their responsibility is uncertain as the Taliban regularly make unsubstantiated claims of attacks on Nato and Afghan forces, and exaggerate casualty numbers in proven strikes.
