The Kremlin said on Friday that the United States should either prove accusations that Russia interfered in the U.S. presidential election by hacking Democratic Party organizations or drop the issue, reports Reuters.

"Either stop talking about it or finally provide some evidence. Otherwise it looks indecent," Kremlin spokesman Dmitry Peskov told reporters in Tokyo, according to Reuters.

Russia has repeatedly denied the hacking allegations.

Barack Obama on Thursday said the United States would retaliate against Russian hacking after the White House accused Vladimir Putin of direct involvement in cyberattacks designed to influence the US election, informs AFP.

The CIA has concluded in a secret assessment that Russia intervened in the 2016 election to help Donald Trump win the presidency, rather than just to undermine confidence in the U.S. electoral system, according to Washington Post.

Trump, who blasted as "ridiculous" the CIA assessment, has continued to question Russian involvement in hacks of damaging Democratic Party emails.
