North Waziristan Agency has 10 tehsils with a population of around 0.4 million people. It has historically been a stronghold for terrorist groups like the TTP and foreign fighters. Operation Zarb-e-Azb was launched in June 2014 to eliminate these terrorist havens and restore government control by clearing the area in stages, with the army, air force, frontier corps, and intelligence agencies participating. So far the operation has killed 570 terrorists and destroyed 98 hideouts while suffering 34 army deaths and 18 injuries. The army is assisting with relief efforts for over 1 million civilians displaced by the operation.
