Russian Internet service providers have blocked access to several major opposition sites and the LiveJournal blog of anti-corruption crusader Alexei Navalny, Lenta.ru reported Thursday.
The Federal Service for Mass Communications and IT Oversight said Thursday that access to the grani.ru, kasparov.ru and ej.ru news sites had been restricted because of "calls for participation in unauthorized rallies."
According to the Twitter account of Navalny, who is under house arrest, some providers have already blocked access to his LiveJournal blog. The telecommunications watchdog said that the blog was being written in violation of the conditions of Navalny's house arrest.
Irina Vorobyova, a journalist at Ekho Moskvy, wrote on Twitter that the radio station's site had also been blocked by Internet service provider AKADO. The reasons of the measure were not clear.
