Ezzatullah, an inhabitant of the area, told Pajhwok Afghan News the airstrike was carried out in the Muradabad area of the city on Saturday evening. But he was unaware who conducted the raid.
He said five members of a family, including a woman and children, were killed and three others belonging to another family injured during the bombardment.
Tirinkot Civil Hospital Director Dr. Ziaur Rahman, said five injured people had been brought to the hospital from the area. They are currently under treatment.
