The UN refugee agency says the number of South Sudanese refugees in Sudan has reached 263,000, with October 2016 marking the highest monthly arrival rate.

In a statement, the Agency says due to the continuing insecurity in the country, a steady influx of new refugees fleeing to Sudan is expected throughout December and into next year.

It said majority of the refugees are in the states of White Nile, East Darfur, West Kordofan and Khartoum.
