Shocking Footage has emerged of the moment a high-rise building in the Iranian capital Tehran collapsed while on fire, trapping dozens of firefighters inside.
The video, filmed earlier today, shows the 17-storey structure, formerly one of Iran's highest, falling to the ground as smoke billows out of several floors.
According to reports, around 200 firefighters were battling the blaze in the building this morning, when it suddenly collapsed.
As many as 25 were reportedly trapped inside and are feared dead.
More 200 people have also been injured in the incident.
