A record 65.3 million people were uprooted worldwide last year, many of them fleeing wars only to face walls, tougher laws and xenophobia as they reach borders, the United Nations refugee agency said Monday.

The figure, which jumped from 59.5 million in 2014 and by 50 percent in five years, means that one in every 113 people on the planet is now a refugee, asylum-seeker or internally displaced in a home country.

Fighting in Syria, Afghanistan, Burundi and South Sudan has driven the latest exodus, bringing the total number of refugees to 21.3 million, half of them children, the UNHCR said in its "Global Trends" report marking World Refugee Day.
