Four children were killed while a woman sustained injuries when a mortar shell hit their vehicle on Friday in the Qamarabad area of Bara tehsil in Khyber Agency, local sources said.
The children and woman, who belonged to the same family, were among the 1,500 families that are migrating from Bara tehsil after a deadline was given by the political administration and Frontier Corps to vacate the area before launching a military operation.
The residents were told to move to Peshawar and the Jalozai Camp.
The Shalobar tribe was given 48 hours to leave the area where a military operation against the militants has been started.
UNHCR provincial spokesperson Taimur Khan has told media that 0.23 million people have been shifted to the Jalozai camp. Narrating their ordeals, the displaced people had said that they had faced immense difficulties in shifting to the camp.
