(Newsroom America) -- At least 880 people appear to have died over the past week as their vessels capsized in the Mediterranean, bringing the total fatalities along the dangerous crossing route to 2,510 so far this year.
The UN refugee agency said that comparatively, some 1,855 died in the crossing in the same period in 2015 and 57 in the first five months of 2014.
So far this year, 203,981 people have made the journey on the Mediterranean.
“The odds of being among the dead are currently one in 81,” said William Spindler, spokesperson for the Office of the UN High Commissioner for Refugees (UNHCR).
“This highlights the importance of rescue operations as part of the response to the movement of refugees and migrants in the Mediterranean, and the need for real, safer alternatives for people needing international protection,” he added.
According to new information from people who landed in Augusta over the weekend, 47 people were missing after a raft carrying 125 people from Libya deflated.
Eight others were reported separately to have been lost overboard from another boat, and four deaths were reported after fire aboard another. These figures bring last week's death toll to 880.
The Turkey-Greece route accounted for three quarters of the nearly 204,000 people who made the journey prior to the end of March.
Some 46,714 travelled to Italy. The North Africa-Italy route is dramatically dangerous: 2,119 people, or one in 23, died.
UNHCR is working to better understand the possible reasons and dynamics behind these movements.
The majority of boats departing Libya are at present reported to be leaving from the Sabratah area to the west of Tripoli. And as in the past they remain more crowded than those that have normally been seen on the Turkey-Greece route, often carrying 600 or more passengers, and sometimes being towed by larger fishing boats which in turn puts them at risk, Mr. Spindler said.
According to some unconfirmed accounts, the recent increase in numbers is linked to efforts by smugglers to maximize income before the start of the holy month of Ramadan, in the coming week, he said.
Survivors told that smuggler hubs operating in locations including Niger remains active in feeding people from West Africa through to Libya, where many remain for many months before being put onto boats for the crossing to Europe.
Nigerians and Gambians are the most prominent nationalities travelling from Libya to Italy so far this year. Somalis and Eritreans, who are among countries more commonly associated with refugee movements, accounted for nine per cent and eight per cent respectively.
Reports of trauma from sexual and other forms of gender-based violence among women making the journey – or being trafficked – appear common. Some women have told they were subject to sexual slavery in Libya. Arrivals of unaccompanied children are on the rise.
