Raza identified three held suspects as Mohammed Irshad alias Zahid and Qari Mohammed Hasan, both commanders of AQIS, and Qari Mohammed Akram of the LeJ.

In June 2014, a militant attack on Karachi international airport left 28 people dead, including 10 attackers.

The attack had started when gunmen disguised as police guards stormed the terminal after opening fire with machine guns and a rocket launcher. This attack led to the launching of Operation Zarb-i-Azb in North Waziristan to control growing militancy in the country.
