Cyber-Attack on BBC

(London, England)

A "sophisticated cyber-attack" on the BBC has been linked to Iran's efforts to disrupt the BBC Persian Service.

In a speech Director General Mark Thompson plans to say that the internet attack coincided with efforts to jam two of the service's satellite feeds into Iran.

He will say: "We regard the coincidence of these different attacks as self-evidently suspicious."

Last month Mr Thompson accused Iran of intimidating Persian service workers.

Reporters Without Borders has also complained about Iran's "cyber-army".

The latest revelation follows a blog post by Mr Thompson in February in which he complained of the "repeated jamming of international TV stations such as BBC Persian TV, preventing the Iranian people from accessing a vital source of free information".

In his speech to the Royal Television Society he will note that on the day of the cyber-attack there had also been an attempt to disrupt the Persian Service's London phone-lines by the use of multiple automatic calls.

It appears the Iranian government is testing methods to electronically seal its population from the outside world.
