Pakistan's government announced the start of a full-scale security operation on June 15 in North Waziristan in the Federally Administered Tribal Areas (FATA) to take on rebel strongholds near the Afghan border.
Dubbed "Zarb-e-Azb", the ongoing military operation was launched against Taliban fighters and their allies in the Pakistani tribal areas. According to the United Nations, as of August 2014 the estimated number of displaced people is now more than one million, comprising about 95,000 families.

The majority of the displaced families have sought refuge in Bannu, with some moving to DI Khan, Lakki Marwat, Kohat Karak, Hangu and Charsadda in Khyber Pakhtunkhwa. Official reports have also confirmed the movement of internally displaced people into Sindh province. Humanitarian aid efforts by the government and relief groups are ongoing.

The FATA Disaster Management Authority (FDMA) has established a camp for displaced families from NWA. The camp has been set up in Bakka Khel with a capacity to accommodate 200,000 people.

So far, only a few families have opted to reside in the camp. The reasons for the low number of residents are a lack of privacy, perceived security concerns, and a lack of facilities such as running water and electricity. As a result, most families have preferred to stay with relatives or friends in rented houses.

Since 2008, almost five million people from Khyber Pakhtunkhwa and FATA have been registered as internally displaced people, uprooted in various waves because of military operations or the deterioration of security caused by non-state armed actors.
Latest UN figures show that 1,002,002 people are still displaced and in need of humanitarian assistance and support.
