John Latuma is one of the tens of thousands of South Sudanese stranded in Sudan as they try to make their way home to their newly independent country.
He is stuck in a makeshift camp in Kosti, a port on Sudan’s White Nile hoping to get a barge nearly 1,450km (900 miles) down the river, through the swamps and over the border to Juba, South Sudan’s capital.
“People are stagnant here - no food, no treatment, no drugs - the situation is very bad,” he says.
South Sudan seceded from the north in July, and over the last year more than 340,000 of its new citizens have made the trip home.
But the flow of returnees has slowed, due to money shortages, the dangerous journey and a lack of transport.
Mr Latuma went to Sudan’s capital, Khartoum, 20 years ago during the long north-south civil war, like many South Sudanese.
He has given up his house and job and is now staying in unenviable conditions with some 12,000 other South Sudanese at Kosti, about 300km south of Khartoum, in a way-station designed to hold 1,500 people.
There are not enough toilets, and there are only two clinics providing health services.
One man, Yacob, complains there are not enough drugs.
Although he is on crutches, he insists on hopping through the camp to show me a place he is particularly indignant about, where the shallow pool of slimy water stinks.
The aid agencies would like to put up more buildings to house the influx, but the Sudanese authorities do not want the camp to become permanent.
The numbers here have grown because there are not enough barges to transport all the people wishing to leave.
