Russia's ruling party said it was subjected to a cyber attack during the presidential elections

Russia's ruling United Russia party said on Saturday it was facing a widespread denial-of-service attack – a form of cyberattack that disrupts internet use – against its online presence, and had suspended non-essential services to fend off the attack.

Russian President Vladimir Putin, who is running in Russia's presidential elections as an independent candidate with the support of the United Russia party, has accused Ukraine of seeking to sabotage the elections, in which his victory is almost certain.
