European satellite provider Eutelsat has taken 19 Iranian television and radio broadcasters off the air as a result of European Union sanctions.
Eutelsat spokeswoman Vanessa O'Connor said that the channels operated by Iranian state broadcaster Irib have been blocked for viewers in Europe and elsewhere as of Monday morning.
Eutelsat says a new round of EU sanctions against Iran adopted earlier this year included Irib.
The EU toughened its sanctions against Iran as part of broader efforts to prevent it from developing nuclear weapons.
Iran's Press TV said Iran's broadcasting company could seek legal action against Eutelsat.
Press TV said it is among the channels cut by the Eutelsat decision.
Others include Farsi-language channels for Iranian expatriates and Arabic-language offerings, including the news channel al-Alam. Most are still visible in Iran.
