Newsweek, meanwhile, reported that a Canadian journalist, Maziar Bahari, who has worked for the New York-based magazine in Iran for a decade, was "detained without charge by Iranian authorities and has not been heard from since."
"Newsweek strongly condemns this unwarranted detention, and calls upon the Iranian government to release him immediately," it said in a statement.
The actions came as President Mahmoud Ahmadinejad, whose disputed victory in June 12 presidential elections has touched off a weeklong wave of mass protests, took London and Washington to task in a statement on his website.
"By making hasty comments, you will not have a place in the circle of the Iranian nation's friends," he said. "Therefore, I recommend you to correct your interfering positions."
Foreign Minister Manouchechr Mottaki also complained to foreign diplomats about Western interference, claiming that Britain had worked to sabotage the election.
"Great Britain has plotted against the presidential election for more than two years," Mottaki said, according to state-run Press TV.
"We witnessed an influx of people (from Britain) before the election. Elements linked to the British secret service were flying in in droves."
Iran's supreme leader set the tone for the anti-Western diatribes on Friday as he made his first public appearance since Ahmadinejad's disputed election.
"Today top diplomats of several Western countries who talked to us previously within diplomatic formalities are showing their real face and most of all, the evil British government," Khamenei said.
The Iranian authorities have restricted foreign media coverage of street protests in Tehran, where state media have said at least 17 people have been killed since the disturbances first broke out.
It was unclear what prompted the reported detention of the Newsweek journalist.
"Mr Bahari's coverage of Iran, for Newsweek and other outlets, has always been fair and nuanced, and has given full weight to all sides of the issues. He has worked well with different administrations in Tehran, including the current one," the magazine said.
Earlier Sunday, the Iranian authorities ordered the expulsion within 24 hours of the BBC correspondent.
Leyne stood accused of "supporting the rioters," the Fars news agency reported.
The Mehr news agency said Leyne was summoned by the ministry of culture and Islamic guidance which had expressed particular concern about the election coverage of the BBC's Persian service which it described as an "obvious example of interference in the domestic affairs of the Islamic republic."
It also warned of more stern action against the British media.
"If various British radio and television networks continue to interfere in our country's domestic affairs by broadcasting fake and incorrect reports of Iran or ignoring international journalism ethics, there will be more stern action taken," Mehr quoted the ministry as saying.
Britain, which has spearheaded criticism of Iran's handling of the election, has dismissed Tehran's criticism.
"I reject categorically the idea that the protesters in Iran are manipulated or motivated by foreign countries," Foreign Secretary David Miliband said.
Britain, and other countries, will not be dragged into a "dispute among Iranians about the election results," he said.
"The UK is categorical that it is for the Iranian people to choose their government, and for the Iranian authorities to ensure the fairness of the result and the protection of their own people," he said.
On Saturday US President Barack Obama warned Iranian leaders that "the world is watching."
"The universal rights to assembly and free speech must be respected, and the United States stands with all who seek to exercise those rights," he added.
