KYIV (Reuters) -Ukraine's top mobile phone operator, Kyivstar, started restoring voice services to some clients on Wednesday after its networks were knocked out by a major cyber attack, Kyivstar CEO Oleksandr Komarov said, with data and other services to follow.
The company, which provides services to more than half of Ukraine's population, sustained "huge" damage during the attack on Tuesday, Komarov told Reuters, calling it "the biggest cyber attack on telco infrastructure in the world".
