‘Russia has nothing to do with hackers' attacks on Estonian web-sites’, the Kremlin press office has announced. The reaction comes two days after one of Estonia's newspapers and its second largest bank were attacked by hackers.

Elsewhere in the Internet it was reported that a number of Estonia's official web-sites was blocked for users registered in the Russian Federation.

Estonian Foreign Minister Urmas Paet accused Russia of launching a massive cyber war, putting psychological and virtual pressure on his country.

Russia said the accusations were reckless and reminded that the official website of the Russian President was also attacked a short while ago, allegedly from servers based in Baltic states.
