More than 1 million refugees and migrants came to the European Union this year, while almost 3,700 died or went missing in perilous journeys which reaped huge profit for smugglers, the International Organization for Migration said on Tuesday.
"This is three to four times as many migrants and refugees coming north as we had in 2014, and the deaths have already far surpassed the deaths last year," IOM chief William Lacy Swing told Reuters.
IOM estimates people smugglers in Europe have made $10 billion or more since 2000, maybe much more. "They are certainly getting very well paid for their services," Swing said.
Out of a total of 1,005,504 arrivals to Greece, Bulgaria, Italy, Spain, Malta and Cyprus by Dec. 21, the vast majority -- 816,752 -- arrived by sea in Greece, IOM said.
IOM spokesman Joel Millman said it was impossible to forecast how the flow of migrants would evolve in 2016.
"So much is in the balance, the resolution of the Syrian war, and the disposition of the European border protection moves that are being contemplated," he said.
"We never thought it would reach this level. We just hope people are treated with dignity.
The record movement of people into Europe is a symptom of a record level of disruption around the globe, with numbers of refugees and internally displaced people far surpassing 60 million, UNHCR said last week.
"No wonder you have such a large flux coming north. This is an unprecedented scale of simultaneous complex protracted disasters from the western bulge of Africa to the Himalayas, with very few stable, peaceful spots in between."
UN refugee chief Antonio Guterres called on Friday for a "massive resettlement" of Syrian and other refugees within Europe, to distribute many hundreds of thousands of people before the continent's asylum system crumbles.
