Ten of thousands of people have been killed and over two million displaced since violence broke out in the South Sudan capital, Juba in mid-December 2013.
Along with the 6.3 million Syrians displaced inside the country, these numbers show that a almost two thirds of all Syrians have been forced from their homes, the report said.
- This included 22.5 million refugees, 40.3 million uprooted within their countries and 2.8 million asylum seekers.
The Geneva Convention says countries should accept someone as a refugee if they have fled their own country because of a 'well-founded fear of being persecuted for reasons of race, religion, nationality, membership of a particular social group or political opinion'.
The UN high commissioner for refugees, Filippo Grandi, stated: "By any measure this is an unacceptable number". More than half of these come from just three countries: Syria, Afghanistan and South Sudan.
A record 65.6 million people are either refugees, asylum seekers or internally displaced across the globe, the United Nations refugee agency said on Monday. Leaving aside the long-standing Palestinian refugee situation, Colombians (7.7 million) and Afghans (4.7 million) remained the second and third largest populations, followed by Iraqis (4.2 million) and South Sudanese (the world's fastest growing displaced population with 3.3 million having fled their homes by the end of the year).
The "unprecedented high" reveals that one in every 113 people worldwide is displaced and a person was displaced every three seconds in 2016, half of which were children under age eighteen.
"At the same time, they are not adequately funding reception of refugees in poor host countries", Egeland said.
UNHCR produces its Global Trends report annually ahead of World Refugee Day on June 20. Lebanon, where one in six people is a refugee, continued to host the largest number of refugees relative to its national population.
"Turkey continues to be for the third consecutive year, the largest hosting country", said Grandi.
That number marks a jump of just 300,000 from the end of 2015, but is more than six million higher than at the end of 2014, according to a fresh report published by the United Nations refugee agency.
A Ghanaian UN peacekeeper stands watch as children look on at a protection camp for displaced civilians in Bentiu, South Sudan June 18, 2017. He called the figures a failure of diplomacy, reports BBC News. At least 75,000 asylum claims were received from an unaccompanied child.
However, the total seeking safety across global borders as refugees topped 22.5 million, the highest number seen since UNHCR was founded in 1950 in the aftermath of the Second World War.
- Developing regions host 84 percent of the world's refugees.
In contrast, almost of all of the South Sudanese refugees have sought protection in neighbouring countries such as Uganda, Ethiopia and Sudan.
