At least 34 migrants have died in a shipwreck in the western Mediterranean, which 26 people survived, the UN migration agency said on Tuesday, citing the Moroccan navy and a Spanish aid agency. Morocco’s interior ministry gave lower figures, saying 31 people had been rescued and that 11 bodies had been recovered on Monday All migrants on board the boat came from sub-Saharan Africa, the ministry said in a statement, adding that investigations showed the organizer of the risky crossing was from Mali. “The boat was adrift since Sunday with 60 people aboard. At least 34 have drowned, it looks like there were 26 survivors,” Joel Millman, spokesman of the International Organization for Migration (IOM), told Reuters. The information came from the Moroccan navy and a Spanish non-governmental organization, Caminando Fronteras (Walking Borders), he added. Helena Manelo, founder of Caminando Fronteras, said the Spanish coast guard had called her early on Monday after being contacted by the captain of the boat whom they were unable to understand. The Morocco-based Spanish activist said she alerted Spains maritime rescue service about the sinking dinghy and its approximate location and that 26 survivors were brought ashore 1½ days later in the northern Moroccan town of Nador. Morocco and Spain cooperate closely at the security level to crack down on trafficking networks but they are not doing enough to save lives at sea, Manelo said. In an incident on Oct. 26, the Moroccan navy fired at a speedboat carrying Moroccan migrants after it refused to stop, killing a young woman and injuring three migrants. Commenting on that incident, Morocco’s Prime Minister Saad Eddine El Othmani said the navy had not seen the migrants because they were hiding in the boat. According to the IOM, more than 36,600 migrants arrived in Spain by sea during the first nine months of the year, a jump in the number from previous years that has put a strain on public services. During the same period, more than 360 migrants were reported to have died in the waters separating Spain from the African coast, doubling the figure from the first three quarters of 2017. More than 1,700 have died on the various Mediterranean Sea routes altogether. Many of the migrants who attempt to cross the Straits of Gibraltar, where Africa is closest to the European mainland, carry the mobile phone number of Walking Borders so they can alert the aid group if they encounter trouble. On Tuesday, Spanish rescuers found 423 migrants attempting the dangerous crossing in 10 different boats, the service said, including a dinghy carrying 21 people that was located 50 nautical miles north of the Canary Islands.
