The International Organization for Migration (IOM) of the UN reports that at least 73 migrants are missing and presumed dead after their boat capsized off the coast of Libya.
Only seven people, who are in "extremely dire conditions," are still alive after the shipwreck on Tuesday.
The police and Libyan Red Crescent have so far found 11 bodies.
The IOM has referred to the passageway as "the world's deadliest migratory sea crossing," and the boat was traveling there.
This year alone, more than 130 people have already perished while making the perilous crossing of the Mediterranean Sea.
The Missing Migrants Project of the IOM reported more than 1,450 deaths last year.
The group's spokesperson, Safa Msehli, declared that the situation was intolerable.
In order to reduce dangerous journeys, Ms. Msehli stated that more efforts were required to "increase search and rescue capacity, establish clear and safe disembarkation mechanisms, as well as safe and regular pathways to migration."
