South Sudan's National Anthem Challenges 13 Years After Independence [4:45]

South Sudan is marking 13 years since its secession from Sudan in 2011. Many in the country say its national anthem, composed by students and teachers at Juba University, is difficult to sing. The dean of the School of Arts, Music and Drama says some of the instruments used for composing the national anthem have disappeared. Juliana Siapai reports from Juba.
