A shop clerk working near the collapsed building described the situation at the time of the accident to reporters.

Nearby shops in Sofia:Suddenly, the sirens sounded, and I saw many policemen running down the street, and ambulances drove through the surrounding streets. We quickly hid in the shop. Through the window we could see a lot of dust filling the air.

Moroccan construction worker Kalim:I wanted to see what happened to the building, if there were any of my acquaintances in it, I was also a construction worker, and my co-workers were also working in the building nearby, on the same street.
