Three international broadcasters have condemned Iran for 'deliberate electronic interference' in their broadcasts.
Voice of America, the BBC and German service Deutsche Welle said the new wave of jamming of satellite services began yesterday as Iran marked the 31st anniversary of the Islamic revolution.
In a joint statement, the three say the Iranian authorities were using the same satellite services to broadcast freely around the world while denying their own people programmes coming in from outside.
Earlier, the US accused Iran of an 'information blockade' saying the phone network, text messages and internet had all been blocked.
US State Department spokesman Philip Crowley reiterated US calls on the Iranian leadership to grant citizens what it says are universal rights to gather and express themselves freely.
'It is clear that the Iranian government fears its own people,' Mr Crowley said.
Iranians have a right to have access to information, communicate and express their views, he said.
