S. Sudan Army Repels Machar Forces
The South Sudanese army says it has repelled three rebel attacks on its positions near the strategic town of Bor.
The fighting is the latest reported breach of a ceasefire signed last month.
Thousands have been killed in South Sudan since fighting began in December between supporters of President Salva Kiir and his former deputy Riek Machar.
Bor has changed hands at least three times.
The rebels re-captured Gadiang north of Bor
