Ukraine’s President Petro Poroshenko has imposed a ban on Russia’s biggest social media networks and internet services popular with millions.
His decision is a significant ramping up of sanctions on Ukraine’s neighbour for its annexation of Crimea and the continuing conflict in eastern Ukraine.
Those targeted include social networks VK.com and Odnoklassniki, search engine Yandex and the Mail.ru email service.
Ukrainian service providers have been ordered to block access to the sites.
The companies’ offices in Ukraine will also face asset freezes and other restrictions although it was not immediately clear how the ban on the services would come into force and whether Ukraine had the technical means to enforce it.
