"The allegations against the ambassador of Iran to the UK issued by the Reporters Sans Frontiere (RSF) and carried by some Western media are categorically false and rejected, Iranian mission wrote in its official Twitter account.

"Ambassador Baeidinejad has never threatened anyone, let alone any journalist," it added
