South Sudan’s President Salva Kiir says his forces have recaptured the key town of Bor, days after it was seized by rebels in a week-long conflict.
Forces loyal to Mr Kiir’s ex-deputy Riek Machar were “on the run”, the information minister said. The rebels have not commented on the claim.
There has been a week of fighting amid a struggle between Mr Kiir, an ethnic Dinka, and Mr Machar, of the Nuer.
The UN earlier said that it had reports of at least three mass graves.
It said there was “palpable fear” among civilians that they would be killed on the basis of their ethnicity.
