Nairobi - South Sudan's military spokesperson says a "misunderstanding" between military troops and a local community sparked clashes that killed five troops.
Colonel Philip Aguer said on Saturday that the trainees were members of the Nuer minority, the same ethnic group that killed hundreds of people in Bentiu this month.
A rebel spokesperson claims that huge numbers of Nuer military trainees were killed in the latest incident on Friday.
Rebel Brigadier General Lul Ruai Koang charged that 220 Nuer officers and trainees at Mapel Military Training Centre in Western Bahr El Ghazal state were deliberately killed.
It was impossible to verify either claim. Koang's claims in the past have been wildly exaggerated, but military and government death tolls announced to the public have also sometimes been underreported.
Aguer denied that Koang's claims were true.
