Four Bulgarian Construction Workers Die in Hamburg Scaffolding Collapse, Others Injured and Missing

Collapse in Hamburg's HafenCity district was at one of the city's biggest construction sites; unclear what caused the collapse that occurred from the eighth floor into a lift shaft.

Four Bulgarian construction workers died and several others were injured when scaffolding collapsed from the eighth floor into an elevator shaft at a construction site in the HafenCity district in Hamburg.
The incident occurred at the Uberseequartier, one of the largest construction sites in the city, which is part of major redevelopment that features offices, houses, hotels, and shops.
Initially, the fire department reported five fatalities but later revised this number down. One of the injured is in a critical condition while an unknown number of people are believed to be missing, buried under the debris.
Emergency services, with around 60 personnel, were swiftly on the scene, which was evacuated, and a technically challenging rescue operation is underway.
The cause of the scaffolding collapse remains unclear, but the workers were believed to have been constructing an elevator shaft at the time of the accident.
