A powerful explosion ripped through a fireworks storage facility in Karachi’s densely populated Saddar neighborhood on Thursday, leaving at least 33 people injured and triggering panic across the area.

Local authorities confirmed that the blast originated from a warehouse stocked with pyrotechnic materials. The shockwave damaged nearby homes and businesses, sending debris flying and prompting emergency crews to rush to the scene. Eyewitnesses described a deafening boom followed by chaos as residents scrambled for safety.

Rescue operations are ongoing, with medical teams treating victims for burns, fractures, and other injuries. Officials have launched an investigation into the cause of the explosion, including whether safety protocols were violated in the handling and storage of fireworks.
