Hundreds of Afghans have protested in Mazar-i-Sharif against rising civilian deaths.
Protesters chanted slogans against foreign forces and Afghan President Hamid Karzai after U.S. troops killed two civilians in a pre-dawn raid on July 7 in the northern city's outskirts.
NATO also admitted killing six people with stray artillery on July 8, a day after an airstrike accidently killed five Afghan soldiers.
Meanwhile, a wave of attacks has killed six U.S. troops and at least a dozen civilians in Afghanistan's volatile south and east.
In the eastern border province of Paktia, unidentified gunmen killed 11 Pakistanis who had crossed into Afghanistan to buy supplies.
