The late 1980s saw turbulent ethnic rioting between Sindhis and Muhajirs. On 30 September 1988, militants from the Sindh Progressive Party drove into Muhajir dominated areas in the city, and opened indiscriminate fire in busy crossroads. The so-called "Hyderabad Massacre" resulted in the deaths of over 60 people in a single day, and more than 250 deaths in total. In a backlash, more than 60 Sindhi speaking people were gunned down in Karachi. The city began to divide itself ethnically, and the Muhajir population migrated en masse from Qasimabad and the interior of Sindh into Latifabad. Similarly, Sindhis moved to Qasimabad from Hyderabad and Latifabad. Further ethnic disturbances occurred in May 1990, including a police-led siege of the Pacco Qillo fortress in the center of Hyderabad, in which Muhajir activists claim 150 were killed. 2 bombings on trains in Hyderabad killed 10 people in 2000.
