Fighting kills at least 25 in oil region of South Sudan

Rebels in South Sudan attacked government forces in Unity State, where oil fields have been abandoned due to fighting, and 25 people including civilians were killed, a local government official said on Tuesday. South Sudan, which gained independence from Sudan in 2011 after protracted bloodshed, fell into civil war in late 2013 with troops loyal to President Salva Kiir fighting those of the ex-vice president he sacked, Riek Machar.
