Russian President Vladimir Putin has told Washington to send him hard evidence that his citizens meddled in US elections, mocking accusations to date as "yelling and hollering in the United States Congress".
The office of US special counsel Robert Mueller charged 13 Russians and three firms last month with interfering in the 2016 presidential vote, as part of what it called a conspiracy to support Donald Trump and disparage Hillary Clinton.
"I have to see first what they've done. Give us materials, give us information," Mr Putin said in an interview with NBC TV aired late on Friday.
"We cannot respond to that if they do not violate Russian laws," Mr Putin told NBC's Megyn Kelly, when asked whether Moscow would take action against the named individuals.

Ms Kelly listed some of the accusations of Russian interference made by Mr Mueller's office and other US officials, including the spreading of false information online.
"With all due respect for you personally, with all due respect for Congress, you must have people with legal degrees, 100 percent you do," Mr Putin said smiling.
He said US authorities should send Russia's general prosecutor an official request.
"This has to go through official channels, not through the press or yelling and hollering in the United States Congress," Mr Putin said.
Recent reports have exposed Russia's alleged 'troll farms' - hundreds of people employed to engage in debate online, posing as Americans. They also are reported to have organised protests and counter-protests to cause divisions amongst Americans.
The broadcast came a day after Mr Putin announced an array of new nuclear weapons, in one of his most bellicose speeches in years, saying they could hit almost any point in the world and evade a US-built missile shield.
Mr Putin is standing in March 18 elections that polls indicate he should win easily.
