Dozens of firefighters were killed when a high-rise building collapsed after a blaze in Iran's capital, state-run Press TV reported Thursday.
The broadcaster put the death toll at 30 at Tehran's iconic Plasco building. It gave no source for the information. NBC News could not independently confirm Press TV's report.
Iranian authorities did not immediately release definitive casualty figures.
However, Reuters reported that Tehran Mayor Mohammad Baqer Qalibaf was quoted by a state-run TV outlet that "about 25 firefighters are trapped inside and rescue teams are trying to get them out."
