Russia Says US Hacking Claims Indecent without Evidence

US President Barack Obama has vowed to take action against Russia for its alleged interference in the US presidential election campaign.
"We need to take action and we will," he told US public radio network NPR.
Russia stands accused by the US of hacking the emails of the Democratic Party and a key Hillary Clinton aide, which the Kremlin strongly denies.
Republican President-elect Donald Trump has also dismissed the claim as "ridiculous" and politically motivated.
