The Airports Security Force forms the cornerstone of aviation infrastructure protection in Pakistan
Airports in Pakistan are adding security measures as they face the constant threat of terrorist attacks. The terminal facing the largest threat is Bacha Khan International Airport in Peshawar, the capital of Khyber Pakhtunkhwa province, which has endured a number of terrorist and insurgent attacks from Islamist groups such as Tehrik-e-Taliban Pakistan (TTP) and Lashkar-e-Tayyiba (LeT).
The authorities at Bacha Khan have cause to be concerned about security. Five suicide bombers from the TTP mounted an attack on the airport in December 2012, killing nine people (three of the militants were killed in a subsequent police operation).
