Iran says it has dismantled several U.S.-backed cyber warfare networks that were gathering information on nuclear scientists and provoking unrest in the country.
A judiciary statement says the networks were set up by Iranian opposition groups, including the armed People's Mujahedeen, and that 30 of their members were arrested.
Iran has repeatedly accused the U.S. and Britain of provoking the unrest that followed June's disputed presidential election — charges both countries have denied.
The judiciary said Saturday that the cyber campaign also involved a group seeking to restore Iran's monarchy. The statement said the networks sought to destabilize the Islamic ruling system in Iran, according to the official IRNA news agency.
