US President Barack Obama has vowed
to take action against Russia for its alleged interference in the US
presidential election campaign.

The intelligence agencies say they have overwhelming evidence that Russian hackers linked to the Kremlin were behind the hacks. And on Thursday, a White House spokesman said President Vladimir Putin was involved in the cyber-attacks.
Hours later, Mr Obama said: "I think there's no doubt that when any foreign government tries to impact on the integrity of our elections, that we need to take action and we will, at a time and a place of our own choosing.
"Some of it may be explicit and publicised. Some of it may not be. "Mr Putin is well aware of my feelings about this, because I spoke to him directly about it."
It is not clear what action the US intends to take, with Mr Obama leaving office on 20 January.
The disclosure of emails was embarrassing to the Democratic Party at a crucial point in the election campaign.
The CIA has concluded that Russia's motivation was to sway the election in favour of Mr Trump, but no evidence has been made public.
