Ninety-two police officers vanished after 1992, and their families never learned what happened to them. That statistic alone captures the scale of Operation Clean-up, the armed intelligence program that tore through Karachi between 1992 and 1994 under the codename Blue Fox. What began as an anti-crime directive from Prime Minister Nawaz Sharif became, under his successor Benazir Bhutto, a sweeping campaign that drew in the Sindh Rangers, the ISI, and mechanized army divisions. The targets were ostensibly criminal gangs and arms caches. The reality was far messier.
To understand how Karachi became a battlefield, you have to go back to the 1984 founding of the Muhajir Qaumi Movement by Altaf Hussain, then a student activist at the University of Karachi. The party, later renamed the Muttahida Qaumi Movement in 1997, represented the Muhajirs, Urdu-speaking migrants who had settled in Sindh after the 1947 Partition. According to General Mirza Aslam Beg's memoirs, President Zia-ul-Haq himself supported the MQM's creation to sideline both the Jamaat-e-Islami in Karachi and the Pakistan Peoples Party in rural Sindh. By 1988, the MQM held 13 parliamentary seats. But its alliance with Benazir Bhutto's government soured over the repatriation of Biharis from Bangladesh, and the political fault lines hardened into street violence.
In 1992, the Intelligence Bureau's director-general, retired Brigadier Imtiaz Ahmed, drafted the Clean-up protocol. The operation initially focused on dacoits in rural Sindh. After Sharif's dismissal and Bhutto's return to power in 1993, the program's scope expanded dramatically. The alleged Jinnahpur conspiracy -- a claim that the MQM planned to break Karachi and Hyderabad away from Sindh as a separate province -- provided political justification. The 25th Mechanized Division of V Corps was brought in for support. Rangers conducted search-and-destroy operations across the city, uncovering arms caches and torture chambers. Interior Minister Naseerullah Babar predicted the operation would wrap up by June 1994. It did not end cleanly.
On 19 May 1994, Bhutto convened a meeting at General Headquarters with Chief Minister Abdullah Shah, army chief General Waheed Kakar, and other officials to formalize the operation's final phase. But the aftermath defied any notion of closure. The period is remembered as the bloodiest in Karachi's history, with thousands killed or disappeared. Families of missing MQM workers continued searching for answers years later. By May 1995, armed clashes erupted again between the MQM and Sindh Police, managed by the PPP. The violence had not been cleaned up. It had been redistributed.
Karachi today is a city of over 20 million people, and the scars of the early 1990s remain visible in its political geography. The ethnic tensions between Muhajirs, Pashtuns, Sindhis, and Punjabis that Operation Clean-up was meant to resolve instead calcified into enduring patterns of mistrust. The MQM's subsequent insurrection, lasting until 2016, can be traced directly to the brutality of this period. For the families who lost fathers, brothers, and sons -- whether MQM activists or the 92 police officers who simply disappeared -- the word 'clean-up' carries a bitter irony that no amount of political rhetoric can wash away.

Nearest major airport is Jinnah International Airport (OPKC). Best viewed from medium altitude to appreciate the scale of this megacity. The Lyari River, which runs through several conflict zones, is visible as a narrow channel cutting through dense urban fabric.
