Nato and US airstrikes have killed scores of Afghan civilians this week, residents and officials said today.
The deaths are likely to deepen discontent with foreign forces and the Western-backed Afghan government.
Nato-led and US forces said there are heavy ongoing clashes in Farah province in western Afghanistan and Kunar province in the east and troops in both places had called for air support.
Several residents and the head of a district council in Farah said an air attack in the Bala Boluk area killed 108 civilians. "Women and children have been killed and 13 houses destroyed," head of Bala Boluk district council Haji Khudairam said. "In the bombing, in total, 108 civilians have been killed."
The governor and police chief for Farah province both declined to confirm or deny the reports of civilian deaths.
President Hamid Karzai has repeatedly called for the Nato-led International Security Assistance Force (ISAF) and the separate US force in Afghanistan to coordinate more closely with his troops to curb a spate of civilian deaths from airstrikes.
But Western unwillingness to accept casualties among their own soldiers and a shortage of ground troops means commanders often turn to air power to beat the Taliban and that almost inevitably leads to civilians deaths, military analysts say.
Casualties are also boosting Taliban numbers, analysts say.
Afghan troops backed by coalition soldiers defeated an attempted Taliban ambush in Farah today, a US statement said. The troops "killed over 30 insurgent fighters with accurate small arms fire and precision air strikes," it said.
Residents of Kunar and provincial officials said airstrikes there killed three dozen civilians on Thursday. Then 25 more civilians were killed in another airstrike yesterday while they buried the bodies of those killed the previous day.
ISAF said airstrikes killed "a number" of militants in Kunar yesterday, but denied there were any civilian casualties.
The Afghan Defence Ministry said 37 "terrorists" were killed in Kunar in a joint operation by Afghan and coalition forces. It said initial reports indicated all those killed were armed men, but it was checking reports of civilian deaths.
More than 300 civilians have been killed by Western air strikes in Afghanistan this year, according to Afghan officials and international aid groups. US and NATO military officials say their tactics minimise civilian casualties and accuse the Taliban of using villagers as human shields and sheltering from raids in people's homes.
