United Nations Refugee Agency (UNHCR) has expressed deep concern after at least 144 refugees and migrants were reported dead or missing following a series of maritime tragedies off the coast of Mauritania.
The fatalities occurred during separate incidents involving overcrowded boats attempting the perilous Atlantic crossing towards Spain’s Canary Islands, a journey that has claimed thousands of lives in recent years as desperate people flee conflict, persecution, poverty and limited economic opportunities in search of safety and a better future.
The most recent tragedies, according to UNHCR, occurred between July 14 and July 18 when Mauritanian authorities, in collaboration with humanitarian organisations, conducted three rescue and disembarkation operations in the coastal city of Nouadhibou.
Although 387 people were safely brought ashore during the operations, the agency warned that the devastating loss of life reported by survivors overshadowed the rescues. One of the most tragic cases was a boat that was rescued from Bufaloto, The Gambia, carrying refugees and migrants hoping to reach Spain..
According to UNHCR, its staff was present during all rescue and disembarkation operations, collaborating with humanitarian partners and Mauritanian authorities to identify vulnerable individuals, offer emergency assistance, and evaluate the protection requirements of individuals seeking international refuge. As a reflection of the increasingly diverse character of migrant movements along the Atlantic route, survivors came from a number of West African nations.
The occurrences, according to the organization, serve as a terrible reminder of the huge risks that migrants and refugees still face in spite of increased worldwide awareness of the perils connected with illicit sea crossings and strengthened rescue operations.
“This is a stark reminder that, despite sustained efforts by coastal authorities and humanitarian partners to save lives, the Atlantic route from West Africa towards the Canary Islands remains one of the world’s deadliest mixed movement corridors due to long distances, unpredictable ocean conditions, unseaworthy overcrowded boats and limited access to timely rescue.”

The Atlantic migration corridor has become increasingly prominent in recent years as tighter border controls along Mediterranean routes have pushed many migrants towards the far longer and more hazardous journey to the Canary Islands. Some boats travel more than 2,000 kilometres across open ocean, often carrying insufficient food, drinking water and fuel while relying on vessels ill-equipped for such dangerous voyages.
Although arrivals to the Canary Islands have declined significantly this year, humanitarian organisations warn that lower arrival figures do not necessarily indicate safer migration conditions. Instead, many fear the reduction may reflect an increase in boats disappearing without trace before reaching land.
According to UNHCR, arrivals to the Spanish archipelago have fallen by 61% compared with the same period in 2025, with approximately 4,400 people arriving by 15 July. Across all major maritime migration routes to Europe, more than 40,000 people have reached European shores so far in 2026, compared with 65,407 during the first half of last year.
Despite the decline in arrivals, the agency stressed that deaths and disappearances at sea remain alarmingly high, with numerous incidents occurring far from public attention and often leaving entire boats unaccounted for.
UNHCR Calls for Safe Migration

The most recent maritime catastrophe has rekindled calls for countries to increase international collaboration in order to decrease risky migration while increasing the number of safe and legal routes that refugees and migrants can use.
UNHCR contends that the humanitarian catastrophe developing along the Atlantic route cannot be resolved by rescue efforts alone. Rather, the organization stated that governments need to deal with the underlying issues that continue to push people to take risky maritime trips.
“Concerted efforts need to be made to address the root causes driving refugees and migrants to take these perilous journeys, while providing meaningful and quicker access to legal pathways through higher resettlement quotas, increased labour opportunities and education pathways as alternatives to the dangerous sea crossings.”

The agency emphasised that conflict, insecurity, political instability, economic hardship and limited access to employment continue to push thousands of people from West and Central Africa towards Europe despite the well-documented dangers of the Atlantic crossing.
Mauritania has become one of the most important transit and rescue hubs along this migration corridor. Its strategic location on Africa’s northwestern coast places it directly along the route used by many boats attempting to reach Spain’s Canary Islands.
So far in 2026, authorities in Nouadhibou and the capital, Nouakchott, have recorded 17 rescue and disembarkation operations involving a total of 2,147 rescued individuals. Humanitarian agencies have worked alongside national authorities to provide emergency shelter, food, medical care and protection services for survivors arriving after days or weeks at sea.
The latest rescues illustrate both the effectiveness of coordinated emergency responses and the enormous humanitarian challenge confronting countries situated along the migration route.
For humanitarian organisations, the deaths reported last week serve as another stark reminder that the Atlantic Ocean continues to claim lives even as global attention shifts elsewhere. Entire families continue to disappear without trace, while countless others risk everything in the hope of reaching safety or economic opportunity in Europe.
