A official in Pakistan says a Pakistani air force attack near the Afghan border on Saturday killed 73 civilians.
A military spokesperson earlier insisted that the attack targeted militants.
The official said initial information suggested that the jet had strayed away from the conflict zone and mistook the village for a militant compound.
The BBC reports it's impossible to verify either account because of the remoteness of the region.
The wounded have been moved to hospitals in the nearby city of Peshawar. They are being treated under strict guard.
Many people have died in air strikes in the area over the past 18 months.
Villagers say another strike - by a US drone missile - killed 13 people on Monday.
