Russia's telecommunications and media sector regulator has confirmed that it has Wikipedia on its blacklist of websites.

"It has been on the register [of sites with banned information] for a long time. I don't know why it's only now that they've woken up," Vladimir Pikov, spokesman for the Federal Service for Supervision in the Sphere of Telecommunications, Information Technologies and Mass Communications (Roskomnadzor), told Interfax.

However, "we are interested in cooperation, and we have made this clear more than once," he said.

Earlier, the Twitter microblog of Wikipedia's Russian version carried the tweet: "It's happened finally - we've been put on the black list (twice?) for the article 'Cannabis smoking."
