Over a 1000 South Sudanese returnees traveling to Western Bahr Al Ghazal are stuck in the Sudanese town of Babanusa without enough food or water.
A number of returnees said the train carrying mainly women and children arrived in Babanusa at the start of the week and is not moving.
They claim there is not enough food or water, causing fear that children may go missing as they wander into town to search for food.
The sources said the delay was a result of lengthy inspection procedures by authorities searching transport headed to South Sudan.
