Geneva: At least 90 people were feared dead on Friday in the latest migrant tragedy in the Mediterranean Sea off the coast of Libya, the UN migration agency said. 

"At least 90 migrants are reported to have drowned, when a boat capsized off the coast of Libya this morning", the International Organization for Migration said in a statement. 

It added that "10 bodies are reported to have washed up on Libyan shores", including two Libyan nationals and eight Pakistanis. 

Two survivors from the disaster had swum to shore, while another was rescued by a fishing boat, IOM further said. 

The agency has repeatedly issued warnings over the extreme dangers facing migrants who try to reach Europe via the so-called central Mediterranean route, which connects Libya to Italy.
