Muhammed Amin is beside himself with grief and despair.
His brother, Naveed Memon, was inside Gul Plaza when a massive fire ripped through the densely-packed shopping centre in Pakistan's commercial capital, Karachi.
Like dozens of others, he still hasn't been found.
What should I tell my mother when I go home? What should I tell my nieces? asks Amin.
My nieces are crying for their father - they are asking me why he is late to come home. What should I tell them? How can I tell them that their father is gone?
Housing an estimated 1,200 shops across a basement, mezzanine, and three floors, Gul Plaza was a wholesale market that offered a wide range of cheaply-priced products. The city's residents would frequent it in droves, particularly ahead of festivals, weddings, and other important occasions.
What started the fire is still unknown. But witnesses say the speed at which it spread, a lack of working fire exits, and the density of shoppers exacerbated the disaster.
Rehan Faisal, who owned a bedsheet shop, said he was able to escape because his shop was located near one of the exits.
No-one knew it would spread so much, Faisal added, saying it only took about five to seven minutes for everything to burn before our eyes.
With most of the gates of the shopping centre locked, Shoiab was among the lucky ones. After fainting amid the smoke, he was rescued by a stranger.
Meanwhile, crowds of people looking for their loved ones have gathered around the building, desperate for any news. The confirmed death toll from the fire currently stands at 27, but over 70 remain missing, complicating rescue efforts.
As anger grows regarding the slow emergency response and safety measures, officials respond with promises of investigations into the tragedy and calls for reforms in building safety standards.
