The UN refugee agency on Monday appealed for $1 billion to help provide aid to those fleeing violence in Sudan, saying it expected over 1.8 million to arrive in five neighbouring countries by year-end.
The estimate is about double what UNHCR projected in May shortly after the conflict began.
Already, more than 1 million people have fled Sudan to neighbouring states amid fighting between the Sudanese army and the paramilitary Rapid Support Forces (RSF) in the capital Khartoum and beyond.
