Cyberattack in Ukraine targets government websites

A number of government websites in Ukraine were down on Friday after a huge hacking attack, Ukrainian officials said.

While it wasn't immediately clear who was behind the cyberattack, the disruption came amid heightened tensions with Russia and after talks between Moscow and the West failed to yield any significant progress this week.

Ukrainian Foreign Ministry spokesman Oleg Nikolenko told The Associated Press it was too soon to tell who could have been behind the attack.

"But there is a long record of Russian cyber assaults against Ukraine in the past," he said.

Moscow had previously denied involvement in cyberattacks against Ukraine.
