Battles between ethnic minorities in southern Sudan have killed at least 16 people and injured dozens more, triggering a regional night-time curfew, according to state media on Tuesday.
Fighting broke out Sunday in Kosti, the capital of White Nile state, which borders South Sudan, according to the state-run SUNA news agency.
The clashes were considered as unrelated to the significant military clashes that have erupted across Sudan since April 15 between forces loyal to two opposing generals, claiming at least 750 fatalities.
