Does Iran really hate the BBC that much? It certainly looks that way, according to BBC Director-General, Mark Thompson.
If you're going to launch a full-scale attack, then do it in style - which is exactly what Iran is being accused of, after the BBC pointed fingers claiming the 'sophisticated cyber-attack' was committed by the Iranian authorities.
Thompson alleges that satellite feeds from the BBC into Iran were being jammed, with a barrage of automated calls blocking their London phone lines.
It is expected that the BBC Director-General will use Wednesday's address to the Royal Television Society to outline his concerns regarding Iran's attempts to 'undermine' the service - according to extracts from the speech released by the British Broadcasting Corporation.
"There was a day recently when there was a simultaneous attempt to jam two different satellite feeds of BBC Persian into Iran, to disrupt the service's London phone lines by the use of multiple automatic calls, and a sophisticated cyber-attack," the British broadcaster's chief will announce.
"It is difficult, and may prove impossible, to confirm the source of these attacks, though attempted jamming of BBC services into Iran is nothing new and we regard the coincidence of these different attacks as self-evidently suspicious."
The BBC has already stated that Iranian-based employees working for the London-based facility have already faced strong intimidation.
Thompson explained that he did not wish to reveal any more details regarding the latest incidents but added: "We are taking every step we can, as we always do, to ensure that this vital service continues to reach the people who need it."
