A rubber boat carrying 55 passengers, including two babies, has overturned off the coast of Libya, the UN migration agency says.

The only survivors, two Nigerian women, were rescued by the Libyan authorities on Friday, the International Organisation for Migration (IOM) announced on Monday. The boat was carrying migrants and refugees from various African countries, it said.

The boat sank after taking on water approximately six hours after departing from the coastal city of al-Zawiya in north-western Libya.

The IOM states that almost 500 migrants have been reported dead or missing trying to cross the Mediterranean Sea from Libya so far in 2026.

Libya has become a staging point for migrants from sub-Saharan Africa seeking to reach Europe since long-time leader Muammar Gaddafi was killed in 2011.

Survivors told IOM that the rubber dinghy had departed at around 23:00 local time from al-Zawiya. It overturned several hours later in the early hours of Friday, north of Zuwara.

It is uncertain why it took so long for the news to emerge.

One of the survivors reported losing her husband, while the other mentioned the death of her two babies. IOM teams provided both women with emergency medical care.

In January alone, at least 375 migrants were reported dead or missing following a series of invisible shipwrecks in the central Mediterranean amidst harsh winter weather. The actual toll is feared to be higher.

Despite numerous tragedies, migrants continue attempting the perilous crossing.

Conditions within Libya are documented as dire, with UN human rights officials warning of torture, trafficking, forced labor, extortion, and abuses committed by state and non-state actors.

IOM has called for enhanced international cooperation to dismantle smuggling and trafficking networks and to create safer migration pathways to lessen deaths at sea.

Many vessels that sink often go unreported, leaving families without information about their lost loved ones.

Countries including the UK, Spain, Norway, and Sierra Leone have urged Libya to close detention centers where rights groups claim migrants have been tortured, abused, or killed.
