* UNHCR reports surge in perilous migration
* People-smuggling flourishing in Mediterranean
* Libyan turmoil exacerbates problem

GENEVA, Aug 26 (Reuters) - Nearly 2,000 people fleeing Africa and the Middle East have drowned in the Mediterranean this year, most of them in the past three months as they tried to reach Europe from Libya, the United Nations refugee agency said on Tuesday.
“In all, we believe that 1,889 people have perished this year while making such journeys, 1,600 of them since the start of June,” UNHCR spokeswoman Melissa Fleming told a news briefing.
Earlier on Tuesday, the Italian navy said it had rescued 364 would-be migrants in a two-day effort after their crowded fishing boat sank off Libya. The bodies of 24 who had drowned were recovered.
Violent political turmoil in Libya - which has long been a major departure point for people trying to reach Europe by sea - has exacerbated the problem, the Geneva-based agency said.
Libya’s worsening security situation “has fostered the growth of people-smuggling operations, but also prompted refugees and migrants living there to decide to risk the sea rather than stay in a conflict zone,” the UNHCR said.
The UNHCR death toll includes more than 300 people who died in three separate incidents since Aug. 22 when boats capsized off the Libyan coast.
A total of 124,380 boat people - largely fleeing war, violence and persecution, the agency says - have landed in Europe since January, many after being rescued by an Italian navy and coast guard operation dubbed “Mare Nostrum”, or “Our Sea”.
Italy now hosts over 108,000 boat people, far more than any country in the region. Greece has nearly 15,000 either rescued or picked up on its sea borders, while some 1,800 are in Spain and over 300 in Malta.
Some 14,000 who reached Italy in the first seven months of the year are under 18 and 8,600 of them travelled alone or were separated from their families on the way, the UNHCR said.
The figures show a strong surge in migrant traffic - and deaths - over the last three years. While some 1,500 died in 2011, in 2012 that number fell to 500, and last year it was just over 600 - all three for the full 12 months.
Migrants who reached Europe by sea numbered some 69,000 in 2011, 22,500 in 2012 and 60,000 last year, the U.N. agency said. (Additional reporting by Isla Binnie in Rome; Editing by Robin Pomeroy)
