North Korea has executed Chang Song-thaek, the once-powerful uncle of the country's leader Kim Jong-Un.
State media said he had been executed after being purged for acts of treachery, and described him as a "wicked political careerist, trickster and traitor".
The White House said it was another example of the regime's extreme brutality.
