South Sudan president Salva Kiir says the attempted coup which saw gun fire in the city overnight has been quashed.
Mr Kiir told reporters in the capital Juba that the government was in full control and announced a night time curfew.
Tensions have been high in South Sudan – the world’s youngest country – since President Kiir dismissed his entire cabinet, including his deputy Riek Machar, in July in an apparent power struggle.
Mr Machar had indicated he planned to contest the presidential elections in 2015.
The country’s Foreign Minister Barnaba Marial Benjamin said a group of disgruntled soldiers and politicians led by former vice president Marchar had attempted to overthrow the government.
He said some troops within the main army base raided the weapons store and were repulsed. Benjamin says casualties from fighting Monday morning are still unknown.
He says some politicians have been arrested but could not confirm if former Vice President Riek Machar, who he said led the attempt, was among them,US Today reported
