Survivors of a building collapse that killed 27 people in the Pakistani city of Karachi were trying on Monday to come to terms with the loss of loved ones and their homes.

Officials say a multistory building has collapsed in Pakistan’s southern port city of Karachi, killing at least six people and injuring several others.

The number of casualties rose to 27 after Pakistani authorities declared the rescue operations concluded after the collapse of a multistory residential building in Karachi.
