Khushab (Urdu: خُوشاب), is a city as well as a district in the Punjab province of Pakistan. The word Khushab means sweet water. Khushab city also serves as the headquarters of Khushab Tehsil an administrative subdivision of the district Khushab.
The city of Khushab is home to the Khushab Nuclear Complex, a critical part of the Pakistan's Special Weapons Program, which has come under much heated scrutiny.
On March 21, 2000, The Christian Science Monitor published an article written by Alexander Colhoun, a high-resolution aerial satellite photo revealed a nuclear reactor, Khushab Nuclear Complex, and a missile base in the city of Khushab. These pictures had mixed views, one of the expression of power that could shackle or reshape diplomatic landscapes of a region and another of the ethical question about the usage of satellite imagery in terms of privacy and national sovereignty of a nuclear-capable nation. The report was published at a time when American President Bill Clinton was due to visit India and sparked concerns worldwide.
Khushab is a combination of two Persian words: khush (Persian: خوش) meaning sweet or tasty and aab (Persian: آب) meaning water. A common belief is that the Persians, from the west, first used the word khush-aab in admiration of the sweet and tasty water found in the historical city situated on the bank of Jhelum River. With time the city started to be known as Khushab.
