“The plane chased them, the insurgents entered a street where children were playing and, as a result of its shooting, seven people have been killed, including six children, and two girls also have been injured,” Mr. Ayoubi said. The victims were members of two families.

Abdul Samad, an uncle of four of the children who were killed, disputed the government’s version of the attack. He said his relatives were working in fields near their village when they were attacked without warning by an aircraft.

His brother-in-law, Mohammad Rahim, 50, had his two sons and three daughters with him. They were between 4 and 12 years old and all were killed, except an 8-year-old daughter who was badly wounded, Mr. Samad said.

“There were no Taliban in the field; this is a baseless allegation that the Taliban were planting mines,” Mr. Samad said. “I have been to the scene and haven’t found a single bit of evidence of bombs or any other weapons. The Americans did a serious crime against innocent children, they will never ever be forgiven.”

American soldiers have destroyed numerous dwellings in Zhare to deny insurgents hiding places, and they have also built new roads across farmland because existing ones were so heavily mined. Residents were quickly compensated by the military, however, and in recent months the area, one of several districts near the city of Kandahar that were once Taliban strongholds, has been relatively quiet.
