What Really Happened at Arabella Plaza?
- 3 Dead, 17 Injured After an Explosion at Arabella Plaza in New Cairo
Early reports pointed to different possible causes of the blast, including claims that an elevator had exploded.
Conflicting accounts emerged in the hours after the explosion, while authorities continued investigating what caused the deadly incident.

Authorities later identified a helium cylinder inside a ground-floor gift shop as the source of the explosion.
But what caused the helium cylinder to explode in the first place?
The Public Prosecution has opened an investigation into the incident, examining the scene and the circumstances surrounding the explosion. Authorities are also looking into the licenses and safety requirements of the mall and the shop where the blast occurred.
While the helium cylinder has been identified as the source of the explosion, the circumstances that caused it to explode have yet to be fully established. Was the cylinder damaged, improperly stored or exposed to heat or pressure? Or could another safety issue have contributed to the incident?
These questions are now part of the investigation, particularly because the explosion occurred inside a busy commercial space where employees and visitors were present.
As the investigation continues, understanding what caused the cylinder to explode could be just as important as identifying the source of the blast. It could help determine whether the incident was an unexpected accident or whether better safety measures could have prevented the tragedy
