A record 65.6 million people are either refugees, asylum seekers or internally displaced across the globe, the UN refugee agency said on Monday.
The estimated figure for the end of 2016 is an increase of 300,000 on 2015, according to its annual report.
It is a smaller increase than 2014-15, when the figure rose by five million, reports the BBC.
"The world seems to have become unable to make peace," Grandi said.
Grandi also warned of the burden being placed on many of the world's poorest states, as some 84 per cent of the world's displaced people are living in poor and middle-income countries, the BBC reported.
