Reports of a suspected drone strike in Zangara, South Waziristan emerged late on Wednesday night.
The reports, based on local reports, said that the incident took place in a marketplace around 6 pm. Reports also said two injured children were brought to Saratoga Hospital 30km away, where they succumbed to their wounds.
The administration said that investigations into the incident were continuing but nothing could be clearly said about the nature of the attack.
If confirmed as a drone attack, it would be the first in Pakistan since 2018.
Locals said that the attack was indeed a drone attack and the unmanned aircraft could be heard buzzing in the area.
Between 2004 and 2018, the US carried out over 400 drone strikes in Pakistan. While they eliminated many major terrorists including two successive heads of the Tehreek-e-Taliban Pakistan, Baitullah Mehsud and Hakimullah Mehsud, civilians also died in thousands.
