The relentless civil war in Syria and a surge of South Sudanese fleeing the collapse of peace efforts in their country helped propel the global population of displaced people to a postwar record in 2016, the United Nations refugee agency said Monday.

The agency’s annual Global Trends report, a statistical assessment of refugees, asylum seekers and people forcibly displaced from their homes, reflected a worsening of conflict, mayhem and persecution.

The new total of 65.6 million people displaced from their homes is 300,000 higher than the 2015 number, which had been the highest since World War II and its aftermath.

“By any measure this is an unacceptable number, and it speaks louder than ever to the need for solidarity and common purpose in preventing and resolving crises, and ensuring together that the world’s refugees, internally displaced and asylum seekers are properly protected and cared for while solutions are pursued,” Filippo Grandi, the United Nations high commissioner for refugees, said in releasing the findings.
