Three U.S. soldiers and a military dog have been killed in Taliban attack in Afghanistan.
The NATO-led International Security Assstance Force (ISAF) said the attack had taken place in Helmand Province on June 20 and was caused by improvised explosive device.
Taliban militants later claimed responsibility for the attack.
The last major incident involving NATO troops was 10 days ago, when five U.S. soldiers were killed in an accidental "friendly fire" air strike in Zabul Province during clashes with insurgents.
ISAF will end its combat mission later this year, leaving the Afghan police and army to take on full responsibility for battling the resilient Taliban insurgency.
