MOSCOW, Jan. 12 (Xinhua) -- The Kremlin said Thursday that Moscow considered allegations of its involvement in hacker attacks on the United States as "stupidity."

"I do not remember how many dozens of times we have repeated and at what levels that we categorically deny any charges against us in this regard, as we believe it is a sheer stupidity," Kremlin spokesman Dmitry Peskov was quoted as saying by RIA Novosti news agency.

He added that this issue "has become a real hysteria. As we know, in hysteria it is not possible to find a rational kernel, we have to wait until it is over."

Peskov made the remarks in response to the comment made by U.S. President-elect Donald Trump's pick for secretary of state Rex Tillerson Wednesday that it was a "fair assumption" that Putin could be involved in the hacker attacks.

U.S. intelligence agencies last week published part of a classified report claiming that Putin had ordered an influence campaign in 2016 involving hackers to secure Trump's victory in the presidential elections.

Peskov said Moscow believed that many statements in this report were "fake and unprofessional information."
