Iran's semi-official ILNA news agency is reporting that the final death toll in the deadly collapse of a burning building in the Iranian capital is 26, including 16 firefighters.

Hassan Abbasi, public relations director of the Tehran Emergency Center told the state-run IRNA news agency that 235 were wounded at the Plasco building fire and collapse in Tehran on Thursday.

Authorities described the building, built more than five decades ago, as having a weak structure.

Interior Minister Abdolreza Rahmani Fazli says an electric short-circuit was the major cause of the blaze.

The fire and subsequent collapse was the worst such disaster in Tehran since 2005, when a blaze at a historic mosque killed 59.
