Nairobi - The US ambassador to the UN says the United States had feared a killing spree in Libya was about to happen earlier this year along the lines of Rwanda's 1994 genocide.
Ambassador Susan Rice said on Wednesday she heard the "strong echoes of 1994" when then-Libyan leader Muammar Gaddafi said his forces would kill rebel supporters in Benghazi.
President Barack Obama was determined not to watch "another predictable horror unfold," she says.
Rice said that the world failed to save civilians in Rwanda and Sudan's Darfur region, but did not fail in Libya. Rebel forces - supported by US and Nato air power - closed in on Gaddafi and killed him in October.
More than 500 000 Rwandans were slaughtered in that country's 1994 genocide.
