US Secretary of State John Kerry speaks during a press conference at the US embassy in Juba, South Sudan, Friday May 2, 2014. 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.
