GENEVA: More than one million migrants and refugees reached Europe this year, including over 970,000 who made the dangerous journey across the Mediterranean, the UN refugee agency said Tuesday.

The new figures, jointly released by the UNHCR and the International Organization for Migration (IOM), listed migrant arrivals in six European countries since January 1, with the vast majority of people — 821,008 — landing in Greece.

A total of 3,692 migrants died or disappeared crossing the sea, IOM said.

“The number of people displaced by war and conflict is the highest seen in Western and Central Europe since the 1990s,” the UNHCR said, referring to the conflicts in the former Yugoslavia that decade.

Half of those who made it to Europe this year were Syrians fleeing their country’s brutal civil war, the UNHCR said, underscoring the conflict’s dominant role in fueling Europe’s migrant crisis.

Afghans made up 20 percent of the group, while seven percent of arrivals were Iraqis.

After Greece, Italy received the second highest number of migrants, with 150,317 people reaching its territory this year, all by sea.

This marked a slight declined from 2014, when 170,000 people landed in Italy after crossing the Mediterranean from North Africa.

Rounding out the group of European countries that saw migrant arrivals in 2015 was Bulgaria (29,959), Spain (3,845), Cyprus (269) and Malta (106).
