Radio Farda received video evidence from the scene of what is said to be the location where the daughter of Iran's ambassador in Moscow died, refuting claims by the embassy that she died of a "brain stroke".

Reporters of Radio Free Europe/Radio Liberty (RFE/RL), the parent organization of Radio Farda visited the street where it was reported earlier Arefe Sanaei fell from a ninth-floor window and hit a parked Renault car.

The reporters saw the car near the Iranian embassy with a dent on its roof and traces of blood nearby.

Earlier, Russia's Interfax news agency had reported that the daughter of Iran’s ambassador committed suicide October 22.

"The young woman was suffering from depression and was taking medication prescribed to her by Iranian doctors. The young woman committed suicide on Tuesday morning," a source told Interfax.

The Iranian embassy announced Arefe Sanaei’s death on social media but denied suicide was the cause, instead saying she died of a “brain stroke”.

The embassy statement was issued after a local TV station reported that the ambassador’s daughter fell from a ninth-floor window on a Renault car and died.

But the video evidence obtained by RFE/RL's Russian-language Current Time TV clearly confirms reports in local media that Arefe Sanaei fell on a car in the street. Evidently, some clean-up work had been done on that location but still traces of blood were visible.

A witness also told Current Time's reporter that a body was found next to the damaged car.

Psychiatric illness and suicide are considered taboos among many Iranians and families often prefer not speak about them.

She was 28 and her maternal grandfather Ali Younesi was Iran’s intelligence minister during Mohammad Khatami’s presidency (1997-2005).

Her father Mehdi Sanaei was a diplomat in Central Asian countries before being appointed as ambassador to Russia. Her Instagram page says she grew up in Kazakhstan and Russia and studied in London.
