WARNING: This report contains extremely graphic images from the start.
The White House has strongly condemned the massacre of civilians in South Sudan calling it a betrayal of the people by their leaders.
Rebels have denied a UN report that they killed hundreds of civilians after taking over the oil hub of Bentiu last week.
China, a major investor in South Sudan's oil industry, also expressed concern about the violence.
