He directed Commissioner Karachi to steadily conduct rescue activities and using all resources to bring persons out of the debris.
Ismail said that Malir-like incidents exposed poor performance of Sindh Building Control Authority (SBCA) and Malir Development Authority (MDA) as the departments were only authorised to allow constructions of such buildings.
Earlier in the day, a three-story residential building collapsed in Karachi's Jafar-e-Tayyar and two persons lost their lives in the incident.
Authorities have reached the spot to rescue the multiple persons trapped inside.
