According to initial information the civilians, including a child, were killed by the alliance forces, he said, adding that the deaths sparked a demonstration by the local villagers, who blocked the highway linking the capital city to southern province of Kandahar for around an hour.
The governor condemned the killings. NATO military said they were investigating the incident.

Also in Kandahar, a photographer for The New York Times was seriously injured when he stepped on a mine in Arghandab district on Saturday, the newspaper said.
