Six killed in massive fire at Pakistan shopping centre

Firefighters in Pakistan's largest city are fighting to extinguish a massive blaze ‍that killed six people and reduced parts of a shopping ​mall to rubble in Karachi's historic downtown.

Videos showed flames ⁠rising from the building as firefighters laboured through the night to stop the fire from spreading in the dense business district on Sunday.

Hundreds of people had gathered around the building, including ‌distraught store owners whose ​businesses had turned to ash.

The fire erupted ‍on Saturday night, with rescue services receiving a call at 10.38pm reporting ground-floor shops at Gul Plaza were ablaze.

"When we arrived, the fire from the ground floor ​had spread to the upper floors, ‌and almost the entire building was already engulfed in flames," Rescue 1122 ​spokesman Hassanul Haseeb Khan told Reuters.

Police surgeon Dr Summaiya Syed ‍said six bodies had been brought to Karachi's Civil Hospital, along with 11 people who had been injured, adding ​that ​police were "invoking mass disaster protocols".

Images ​of the mall's interior revealed ​the charred remains of stores and a bright orange glow as flames continued to rise throughout the building.

Local media reported parts of the building had started to collapse and rescue officials feared the whole structure could come down.
