At least four soldiers and 10 militia members were killed in fighting in an area of South Sudan where previous clashes led to the arrest of First Vice President Riek Machar, the military said on Tuesday.
The arrest of Machar - a longtime rival of President Salva Kiir - in March prompted international calls for restraint and stirred fears of a return to civil war between Kiir's Dinka forces and Nuer fighters loyal to Machar.
