Obama vows action against Russia over election hacks

US President Barack Obama has vowed to take action against Russia for its alleged interference in the US presidential election campaign.
 
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.
 
The intelligence agencies say they have overwhelming evidence that Russian hackers linked to the Kremlin were behind the hacks.

A White House spokesman said President Vladimir Putin was involved in the cyber-attacks.
