The governor of Kunar Shuja-ul-mulk Jalala said the incident happened when US-led foreign troops opened fire on a house after Taliban militants fired rockets targeting a military base in the troubled region.
The Western military alliance has yet to comment on the fatal incident, which sent shock waves across the volatile region.
UN observers had reported in the past that Afghan civilians, including women and children, are the main victims of US-led attacks in the war-torn country.
A large number of civilians have been killed or injured at the hands of US-led foreign forces — most of them in nighttime raids and airstrikes. The casualty rate has risen over the past few months, even though the Afghan government had asked foreign forces to make every effort to avoid killing civilians.
The US-backed NATO command has for months ignored residents’ complaints of severe abuses committed by the elite American troops and commandos.
These developments come after Afghan investigators found substantial proof that American Special Forces have been involved in kidnapping, torturing and killing of Afghan civilians across the war-torn country.
Civilian casualties have long been a source of friction between the Afghan government and US-led foreign forces and have dramatically increased anti-US sentiments in Afghanistan.
The United States and its allies invaded Afghanistan in October 2001 as part of Washington’s so-called war on terror. The offensive removed the Taliban from power, but insecurity continues to rise across the country, despite the presence of thousands of US-led troops.
