The Federally Administered Tribal Areas (FATA) were in actuality no-go areas for the Pakistani authorities, where the Pakistani police could not enter. The situation was changed temporarily with the United States invasion of Afghanistan in 2001, when the Pakistani government was supported by U.S. military forces. Currently FATA are no longer a "no-go area" as they have been merged with the Khyber Pakhtunkhwa province.
