Tehran’s fire department said on the day of the collapse that the Plasco building’s managers had been warned that it was unsafe, with corridors and staircases blocked by goods and no fire extinguishers.
Tens of thousands of Iranians have attended the funeral of 16 firemen who were killed when a high-rise building collapsed in Tehran two weeks ago.
They had been battling a blaze in the 17-storey Plasco building when it came crashing down in a matter of seconds.
Four civilians are also known to have died, while six more are still missing.
The tragedy shocked the nation, and the firemen were laid to rest in the “martyrs'” section of a cemetery in the south of the capital.
