More than 100 people in eastern Afghanistan's Ghazni province have been protesting for the second day against the killing of civilians by foreign troops.
Villagers say four civilians, two of them children, were killed when soldiers arriving by helicopter in the middle of the night stormed two houses.
But Nato insists only Taliban fighters were killed in the raid.
