At least 12 buses from Kampala are stuck at Nimule border town following hours of heavy fighting in the South Sudan capital, Juba.
Willy Katende, spokesperson of the bus drivers association, who is now at Nimule, said that the buses arrived at Nimule between 4am and 7:30am on Monday, but were not allowed to cross the border into South Sudan.
Katende said that there is no vehicle going in or out of South Sudan at the moment.
He further said that the buses that should have left Juba are still stuck in the Capital where fighting is still ongoing.
The fighting broke out at about 10pm on Sunday in what appears to be a widening split between President Salva Kiir and sacked vice president Riek Machar.
