Three firefighters have sustained injuries whilst extinguishing a commercial building fire in Karaj, west of Tehran, that broke out Thursday night.

The incident at Taleghani Tower was successfully brought under control by the firefighting team, local authorities announced.

Mehdi Samiei, the spokesperson for the Fire and Safety Services of Karaj Municipality said, "The fire originated on the 16th floor of a commercial complex, and through the efforts of firefighting teams, it was extinguished."

"Unfortunately, three firefighters sustained injuries during the firefighting operation," he added. Samiei also disclosed that an investigative team is onsite, scrutinizing the circumstances that led to the incident.

Furthermore, he highlighted the scale of the response, stating, "A total of fifty personnel, complemented by fifteen emergency vehicles from twelve stations, were dispatched to the scene to engage in firefighting and rescue operations."

Although hundreds of buildings in Tehran are at high-risk of fire, authorities are withholding the list of endangered buildings to avoid public concern.

In January 2017, the Plasco Building's fire caused its 20-story collapse, claiming 20 firefighter lives and injuring 70 more.
