Tehran: The death toll from a fire at a commercial complex near Iran's capital Tehran has risen to 11, while at least 41 people were injured, Iranian authorities said Wednesday.

According to Anadolu Agency, Shahriar Governor Sajjad Baranji reported that the blaze broke out Tuesday evening at the Arghavan complex in Phase 4 of Andisheh, west of the capital. The complex comprises over 250 commercial units and 50 office units.

Baranji stated that emergency teams from Shahriar and neighboring districts were dispatched shortly after the fire was reported, and firefighting operations commenced immediately. He noted that 41 injured individuals had either been transferred to medical centers or received treatment on site.

On Tuesday, the head of Andisheh's Fire Department assured that all individuals trapped by flames and smoke had been evacuated safely and that the building was fully cleared. The official attributed the rapid spread of the fire to the building's composite facade, which facilitated the quick movement of flames across the exterior.

The cause of the fire remains under investigation.
