A gas cylinder explosion on Thursday caused a multi-story residential building to collapse in Karachi, Pakistan, killing at least 13 people. Seven children, including a toddler, were among the victims, and emergency crews continue searching for survivors in the debris.

A devastating gas cylinder explosion brought down a multi-story residential building in Pakistan’s largest city Thursday, leaving at least 13 people dead, according to local authorities.
The deadly blast occurred on the ground level of the residential complex located in Soldier Bazaar, a neighborhood on the eastern side of Karachi, the major southern port city, officials reported.
Among the fatalities were seven children, with the youngest victim being just two years old, according to police official Summaiya Syed.
Authorities are still working to determine what caused the gas cylinder to detonate, police stated.
Rescue teams pulled more than a dozen injured survivors from the wreckage, though emergency responders warn additional victims may still be trapped beneath the debris.
This tragedy follows another deadly incident in Karachi just last month, when a massive blaze at a shopping mall claimed more than 70 lives.
