NATO said the strike killed "eight armed enemy combatants."
Former President Hamid Karzai repeatedly clashed with NATO forces over civilian casualties from airstrikes, straining relations as public anger against the coalition grew. There was no immediate response from Afghan President Ashraf Ghani Ahmadzai.
The protesters brought seven corpses to the governor's office in eastern Paktia province, claiming they were civilians killed yesterday during a NATO airstrike in a mountainous area on the outskirts of the city of Gardez. The villagers said the strike targeted eight people collecting firewood and left one man wounded.
Sahee said that there was a dead body of a 12-year-old boy among those brought to the provincial capital.
Protested villagers shouted slogans against the foreign forces that have been in the country since the 2001 U.S.-led invasion. They demanded the Afghan government prevent such attacks in their area.
In a statement, NATO said a "precision strike resulted in the death of eight armed enemy combatants." "No civilian casualties or damage to structures occurred during this operation," NATO said.
Deputy Interior Minister Gen. Ayub Salangi said the attack in the capital killed one civilian and wounded three. NATO said the attack targeted one of its vehicles in Kabul, adding that there were no immediate reports of any casualties among members of the international coalition.
Taliban insurgents claimed responsibility for the attack in an emailed statement.
In Nangarhar province, a suicide bomber killed two Afghan civilians and wounded six in his assault targeting an Afghan army patrol, the Afghan Interior Ministry said in a statement.
