Tensions are rising in the oil-rich east African nation of South Sudan after Riek Machar who serves as a vice president was arrested in the capital.

President Salva Kiir ordered the arrest of Riek Machar, the opposition said, imperiling a 2018 peace deal. Several embassies urged their citizens to leave the country.

Di UN bin dey warn say South Sudan don dey enta anoda civil war afta di kasala between Machar and di president don dey boil dey come for weeks.

Sudan’s army says it has wrested control of the capital Khartoum from a feared militia accused of genocide after ousting it from the Presidential Palace and the city’s airport it had held since the start of a brutal two-year conflict.

Sudan’s army said Wednesday it had recaptured Khartoum’s international airport, and the military chief flew back to the capital for the first time in nearly two years of war, bringing the military closer to regaining full control of the city from the rival Rapid Support Forces paramilitary group.

Sudan’s army recaptured the national capital from the Rapid Support Forces militia, a turning point in a two-year civil war that’s drawn in outside powers and torn the resource-rich North African country apart.
