Minister of Intelligence Mahmoud Alavi said that so far no indications pointing to a terrorist will, or sabotage, have been traced behind the fire-ensued collapse of Plasco Trade Center in downtown Tehran, the capital city of Iran, according to IRNA news agency of the country.

The 17-story building was built in 1962, and it was one of the oldest high-rises in Tehran.

The Plasco Trade Center collapsed on Thursday morning, as firefighters were trying to contain fire in the building.

As per IRNA, five people have lost their lives so far and some 25, most of them firefighters, are still under the rubble.
