MOSCOW -- The Russian Defense Ministry is mocking British Defense Secretary Gavin Williamson for his claim that Moscow has been hatching plans to cripple Britain's infrastructure.

Williamson said in an interview with the Daily Telegraph that Russia has been researching British infrastructure with a view to disrupting it and creating "panic" and "total chaos."

The defense chief, who is widely seen as a possible successor to current British Prime Minister Theresa May as leader of the governing Conservative Party, told the Telegraph that Moscow could cause "thousands and thousands and thousands of deaths" by taking out energy supplies and targeting other infrastructure.

This plotting, Williamson said, is "the real threat... the country is facing at the moment." He added that Russia would be willing to take action against Britain that. "any other nation would see as completely unacceptable".

Ministry spokesman Maj. Gen. Igor Konashenkov on Friday ridiculed Williamson's statement, saying it was worthy of British comedy group Monty Python.

Konashenkov alleged that Williamson talked about the perceived Russian threat to raise his profile. He added that the "silly" claims about Russian plots would merit a medical checkup of their authors.
