Why did the government launch a military crackdown in Karachi in 1992?

The government initiated a military crackdown in Karachi in 1992 in response to the severe levels of lawlessness that had gripped the city during the final quarter of the 20th century.1

This period was marked by a significant rise in both organized crime and brigandage, as well as intense ethnic violence between native Sindhis and muhājirs—immigrants who had arrived from India. While the military campaign was launched to address this instability, it did not achieve significant results until the end of that decade.1
