US marines conduct a night patrol in Sangin Helmand Province on June 9, 2012.
At least 12 Afghan people have been killed in a nighttime attack carried out by the US-led forces in northeastern Afghanistan, Press TV reports.
Witnesses say there six civilians were among those killed in the Monday night attack in Tagab district of Kapisa province.
However, Tagab governor Abdul Qodous Safi said that 12 Taliban militants have been killed and one other has been arrested.
Taliban and the NATO have not commented on the incident.
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.
Similar incidents in the past have led to violent public protests.
The United States and its allies entered the war in Afghanistan in October 2001 as part of Washington’s so-called war on terror. The offensive removed the Taliban from power, but after more than 11 years, the foreign troops have still not been able to establish security in the country.
