Meanwhile, Firefighting Organization Spokesman said all nearby buildings have been evacuated, but the biggest problem is the crowd of people watching, and the shop owners trying to check out their shops. The traffic jam also hinders the rescue operation.
He went on to say that the Firefighting organization had frequently warned the building owners against its poor safety.
“The accident was predictable. We don’t know how long should we suffer for other people’s irresponsibility,” he added.
“The initial firefighting operation was successfully ending when a number of heavy blasts led to the building’s total collapse.
