A senior Swiss diplomat has reportedly been found dead in Tehran after falling from a high-rise building.
Iranian media, quoting emergency services, say she is the first secretary at the Swiss embassy, and fell from the building where she lived.
The Swiss foreign ministry didn't identify the victim, but said an embassy employee had died of an accident.
A spokesman from the Iranian emergency services said the diplomat's body was found by a gardener.
That was after an employee who arrived at her apartment early on Tuesday noticed she was missing - that's according to local news agencies.
Switzerland has represented U.S. diplomatic interests in Iran since Washington and Tehran cut ties shortly after the 1979 Islamic Revolution.
It comes as Iran and world powers continue renewed negotiations over its nuclear program.
