Rebels in South Sudan have seized some oil wells and captured half of the capital of the main oil-producing region, the government and army said on Thursday as African leaders held talks to avert civil war. Kenyan President Uhuru Kenyatta and Ethiopian Prime Minister Hailemariam Desalegn met South Sudan's President Salva Kiir in the capital Juba in an attempt to end nearly two weeks of fighting in the world's newest state.

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.

This past week, in an article reflecting on recent successes and setbacks for lesbian, gay, bisexual and transgender (LGBT) people around the world, I wrote: “There have been retrogressive steps in several countries, including Nigeria, and Uganda where new regressive bills have been proposed, although thankfully, to date, none have passed into law.”

US President Barack Obama has warned South Sudan that Washington and its allies would cut aid to the country over any attempted military coup, amid growing fears of civil war. Obama also urged South Sudan's leaders to help protect US personnel and citizens in the conflict-ravaged country, after four US military service members were wounded when their aircraft were fired upon on Saturday during a mission to evacuate American citizens.

They were an unlikely pair to lead the world’s newest nation — from different tribal groups and different regions, having taken vastly different paths to power. President Salva Kiir, a field commander with little formal education, was known for his black ­cowboy hat. His vice president, Riek Machar, had earned a doctorate in Britain and preferred Western suits.

Uganda's parliament has passed a bill to toughen the punishment for homosexual acts to include life imprisonment in some cases. The anti-homosexuality bill also makes it a crime punishable by a prison sentence not to report gay people. The prime minister opposed the vote, saying not enough MPs were present. The bill has been condemned by world leaders since it was mooted in 2009 - US President Barack Obama called it "odious".

The philanthropist Howard G. Buffett—eldest son of multibillionaire investor Warren Buffett—and Rwandan President Paul Kagame go back a long way. Buffett’s foundation has been active in Africa for years, investing more than $140 million in central Africa’s Great Lakes region, which includes Rwanda. Almost every time Buffett visits Africa, he stops by the Rwandan capital of Kigali to see Kagame.
