Zarb-e-Azb was a joint military operation launched by the Pakistani government in June 2014 in response to the TTP's attack on Karachi airport. Over 30,000 Pakistani soldiers were deployed to target militant groups like the TTP, Haqqani Network, and al-Qaeda operating in the Federally Administered Tribal Areas. While the operation was supported by most political parties and civilians, the TTP responded with several retaliatory attacks including the deadly Peshawar school attack in December 2014 that killed 145 people. The Pakistani military and police intensified counterterrorism efforts, conducting raids that killed many TTP commanders and militants.
