MOSCOW (Reuters) - The Kremlin said on Tuesday it did not understand allegations from Microsoft that hackers linked to Russia’s government had tried to target the websites of two right-wing U.S. think-tanks.

The software giant said it had thwarted the Russia-linked attempts last week, which it suggested showed Moscow was broadening its attacks in the build-up to November mid-term elections.

“We don’t know what hackers they are talking about,” Kremlin spokesman Dmitry Peskov told reporters on a conference call when asked about Microsoft’s accusations.

“... Who exactly are they talking about? We don’t understand what the proof and the basis is for them drawing these kind of conclusions. Such information (proof) is lacking.”
