Afghan officials say they are checking reports of heavy civilian casualties during US coalition air strikes in southern Helmand province Thursday.
The officials say the air strike occurred in the province's northernmost Baghran district. Provincial police chief Mohammad Hussein Andiwal said Friday there were heavy casualties but did not know exactly how many militants and civilians were killed. Baghran district residents say as many as 200 civilians died.
The US military disputed the reports. A military statement said coalition forces conducted what it called a precision air strike against two Taleban commanders conducting a leadership meeting in the district.
The US military said there were no civilians in the area and that the fate of the commanders is unknown.
Some Afghan officials said the strike hit people who had gathered to watch the Taleban hang two men accused of spying for the government. Other reports dispute that account, quoting residents as saying victims were either preparing for picnics or going to a shrine.
Hundreds of civilians have been killed during NATO and US military operations against insurgents. Angry Afghans have protested and President Hamid Karzai has called the situation unacceptable.
The issue is likely to be high on the agenda of an upcoming meeting between President Bush and Mr. Karzai at the Camp David presidential retreat near Washington.
