The blaze erupted on Tuesday in the Arghavan commercial complex in the city of Andisheh, west of Tehran.

Footage broadcast by state television showed a multi-storey building on fire with thick black smoke billowing into the sky.

According to state television, the fire injured 41 people.

The complex had more than 250 commercial units and 50 office units, according to local officials.

The Public and Revolutionary Prosecutor’s Office of Shahriar called for an investigation into the incident to identify possible culprits.

It also issued an arrest warrant for the building’s constructor.

Fires are common in Iran, but they rarely cause casualties.

In June 2020, a powerful explosion caused by gas canisters that caught fire at a clinic in northern Tehran killed at least 19 people.

In January 2017, a fire at the 15-storey Plasco shopping centre in Tehran killed at least 22 people, including 16 firefighters.
