[EX Q]: Sudan has withdrawn its soldiers from Abyei, a disputed border region also claimed by South Sudan, but has left police officers, the United Nations peacekeeping mission said Wednesday. "The mission has confirmed the full withdrawal of the SAF from Abyei area yesterday," said Josephine Guerrero, a spokeswoman for the U.N.'s Department of Peacekeeping Operations in New York, referring to the Sudan Armed Forces. "Armed police forces are still in the area." South Sudan's army spokesman, Philip Aguer, said he is "skeptical" that Sudan has truly pulled troops out. He said he had received reports that the Sudan Armed Forces left two platoons of soldiers dressed in police uniforms in Abyei town, and that two battalions remain about 40 miles away in Diffra, which is the only oil field inside the disputed territory.The U.N. has called for Sudan and South Sudan to withdraw forces from AbyeiA South Sudan army spokesman questions whether Sudan has truly pulled its forces outMany people remain displaced in the disputed border regionSudan and South Sudan have returned to peace talks

[EX Q]: Beijing (CNN) China -- North Korea's only global ally and biggest trading partner -- has put on a stoic face since Pyongyang successfully conducted its sixth nuclear test Sunday. President Xi Jinping didn't mention his country's unruly neighbor at all in his closing address at the BRICS summit of emerging economies Tuesday, or in earlier speeches, although a communique issued by the group expressed deep concern and called for the crisis to be settled peacefully. But the test of a hydrogen bomb couldn't have sat well with China's leader. It's the third time in one year that North Korea has overshadowed a major Chinese event -- previous missile tests coincided with the unveiling of Xi's global economic blueprint at his Belt and Road summit in May and the G20, which China hosted last September.Voices in China diverging from official line on North Korea policyNuclear test seen as an embarrassment to Xi JinpingXi makes no reference to North Korea in closing summit speech

[EX Q]: (CNN) -- President Obama slowly walked across the grounds of Cape Coast Castle, a slave outpost in Ghana where hundreds of thousands of Africans were shipped as human cargo to a life of bondage in the United States, South America and the Caribbean. President Obama and his family toured Cape Coast Castle during their trip to Ghana. "You almost feel as if the walls can speak. You try to project yourself into these incredibly harrowing moments," Obama told CNN's Anderson Cooper. When the president reached the "Door of No Return," an arched gateway with thick doors that would shut behind African men, women and children before they were forced onto slave ships, Obama looked out over the Atlantic Ocean where waves crashed onto rocks. "Obviously there's a sense of what a profound sorrow must've been felt as people were hauled off into the great unknown," he said.Obama's visit to Ghana came weeks after Senate apologized for slaveryDebate still rages over apology; Maryland lawmaker says there's "no need" for oneKatrina Browne learned her ancestors from the North made millions trading slavesIn Ghana, Obama says issue is still relevant: "Capacity for cruelty still exists"
