At least three major international media outlets have accused Tehran of interfering with their broadcasting, while cracking down on foreign programs aired in the Islamic Republic.
The BBC, Deutsche Welle and Voice of America reported jamming that began as Iran marked the 31st anniversary of its Islamic revolution.
"We condemn any jamming of these channels. It contravenes international agreements and is interfering with the free and open flow of international transmissions that are protected by international treaties," the broadcasters said in a joint statement.
"The Iranian authorities are using the same satellite services to broadcast freely around the world including broadcasts in English and Arabic; at the same time they are denying their own people programs coming from the same satellites from the rest of the world," they added.
The United States on Thursday accused Iran of imposing a "near-total information blockade" over the course of the day. The State Department cited evidence that telephone networks had been silenced, SMS messages blocked and that the Internet had been "throttled." The Gmail email system had also been blocked, said sources.
Meanwhile, Iran's supreme leader on Thursday warned the West to stop putting obstacles in his country's path.
State Press TV reported on Friday that Ayatollah Ali Khamenei thanked the tens of millions who gathered to mark the anniversary of the revolution, saying it reflected the nation's strength. "It's time for foreign enemies to wake up and abandon futile efforts to subjugate Iran," he said.
Earlier Thursday, the State Department said that Iranian President Mahmoud Ahmadinejad's announcement that the country has succeeded at creating higher levels of uranium enrichment shows its nuclear intentions are "anything but peaceful."
Ahmadinejad said scientists had succeeded at producing a batch of uranium enrichment at a much higher level that it had previously accomplished. The amount was sufficient for running in nuclear power reactors, but still well below the levels needed for weapons grade uranium.
But Iran's nuclear ambitions continue to draw concerns from the United States and European allies who fear Iran is seeking the capability to build nuclear weapons. Iran has rebuffed diplomatic overtures to resolve the issue and is in defiance of UN Security Council demands that it suspend uranium enrichment.
