The Wah Cantonment Ordnance Complex is home to Pakistan Ordnance Factories, responsible under the Pakistan Ministry of Defence for producing conventional weapons. [1] The facility is also believed to be Pakistan's main nuclear weapons assembly facility, where – allegedly with Chinese assistance – Pakistan has worked on assembling nuclear weapons since the early 1980s.

In August 2008, two suicide bombers detonated their explosives just outside the gates of the Wah Cantonment, killing fifty-nine people and wounding seventy. [3]
