From CBS News:
JUBA, South Sudan — In a stern warning, U.S. Secretary of State John Kerry is urging South Sudan’s warring government and rebel leaders to uphold a months-long promise to embrace a cease-fire or risk the specter of genocide through continued ethnic killings.
Kerry, landing in the capital Juba on Friday, carried the threat of U.S. sanctions against prominent South Sudanese leaders if the rampant violence doesn’t stop. But more than anything, he sought to compel authorities on both sides of the fight to put aside personal and tribal animosities for the good of a nation that declared independence three years ago to escape decades of war.
Now, South Sudan is engulfed in widespread killings that have largely broken down along ethnic lines and are drawing comparisons to genocide.
