"People are still busy bringing out the dead from under the rubble. There are funerals at various places."
Mohammad Khan, a resident of Hyderabad, said the air raids killed seven members of his family, including his brother and five of his brother's children.
Villagers were burying a "lot of dead bodies" on Saturday, he said by telephone.
James Bays, Al Jazeera's correspondent in Afghanistan, said: "It is clear that members of the US-led coalition, probably American special forces, called in the close air support.
"What is not clear is exactly how many people died. It is known that women and children were among the dead, some local leaders say over 100 people were killed."

It said the air raids were in response to attacks on a joint Afghan-coalition patrol.
Major Chris Belcher, a coalition spokesman, said: ""It appears that ANA [Afghan National Army] and coalition forces fired at clearly identified firing positions."
"Remains of some people who apparently were civilians were found among insurgent fighters who were killed in firing positions in a trench line."
He alleged that Taliban fighters had hidden among civilians.
Major John Thomas, a spokesman for Nato's International Security Assistance Force [Isaf], said it was aware there were "probably" some civilian casualties but said: "We have no evidence to corroborate some of the large numbers we have seen reported in the press."
Civilian deaths caused by US and Nato-led troops have infuriated Afghans.
The killings come a week after Hamid Kharzai, the Afghan president, criticised Nato and the US-led coalition, saying: "The extreme use of force, the disproportionate use of force, to a situation and the lack of co-ordination with the Afghan government is causing these casualties."
He condemned the forces for carelessness and viewing Afghan lives as "cheap". He also blamed the Taliban for using civilians as human shields.
