The United Nations Mission in South Sudan (UNMISS) said Tuesday it has "mounting evidence" that serious human rights abuses, including targeted ethnic killings, have been committed in the world's newest nation in the 16 days since violence broke out in Juba. The alleged atrocities include extra-judicial killings of civilians and captured soldiers, massive displacements and arbitrary detentions, often on ethnic grounds, UNMISS said in a statement.

South Sudanese rebel leader Riek Machar and the nation's president Salva Kiir have agreed to negotiate after two weeks of bitter fighting that has brought the world's newest nation to the brink of an extended civil war. Yet fighting is apparently continuing as government forces under Mr. Kiir were engaged at least up to a deadline designed to trigger military intervention by neighboring African states, backed by the international community.

Elodiane Baalbe hid underneath her bed as gunfire echoed around her on Christmas Day in the capital of Central African Republic. When it finally died down on Thursday, she made a dash for safety, hiding behind houses as she fled her neighbourhood. On her way out she passed the calcified car of a unit of Chadian peacekeepers, the charred body of one soldier still upright in the vehicle inside. The sight was so horrifying that she looked away immediately. “I had my 3-year-old on my back. I looked for a second, and then I kept running,” she said.

On the face of it, China’s recent declaration of an air defense identification zone (ADIZ) extending to territories that it does not control has nothing in common with America’s arrest and strip-search of a New York-based Indian diplomat for allegedly underpaying a housekeeper she had brought with her from India. In fact, these episodes epitomize both powers’ unilateralist approach to international law.

The Pentagon has announced it is sending 150 U.S. Marines to Africa, for a possible mission to evacuate Americans in South Sudan, where political and ethnic violence has claimed hundreds of lives and left hundreds of thousands homeless. NPR's Tom Bowman says the Marines are being sent from Spain to beef up the U.S. military presence at a base in Eastern Africa. Officials say they'll await orders and could head into South Sudan.

The United States says all members of the U.N. Security Council support a proposal to send 5,500 peacekeepers to South Sudan in order to protect civilians from worsening violence. The Security Council is due to vote Tuesday afternoon on a resolution to transfer troops from other U.N. missions in Africa following the proposal from U.N. chief Ban Ki-moon.

Nelson Mandela and Mother Teresa will be the key figures in a UN campaign to promote peace in Colombia. The United Nations representative in Colombia, Fabrizio Hochschild, announced on Thursday that that the “Peace is Mine” initiative aims to promote peace in the country through the iconic use of these “two huge global figures.”

Patterns of global migration and remittances have shifted in recent decades, even as both the number of immigrants and the amount of money they send home have grown, according to a new Pew Research Center analysis of data from the United Nations and the World Bank. A rising share of international migrants now lives in today’s high-income countries such as the United States and Germany, while a growing share was born in today’s middle-income nations such as India and Mexico, the analysis finds.
