“The investigation focused on an Iraqi-Kurdish network suspected of smuggling Middle Eastern and East African irregular migrants from France to the U.K. with the use of low-quality inflatable boats,” the EU’s law enforcement agency said.

The suspects of the investigation, launched at the end of 2022, organized the purchase, storage and transportation of the inflatable boats, mainly of Chinese origin, that they later used to smuggle migrants from the beaches near the French city of Calais toward the U.K..

On average, the gang would put 50 migrants in the boats suited for a maximum of 10 passengers, charging between EUR 1,000-3,000 (USD 1,081-3,242) per migrant, Europol said.

Wave, the operational task force behind the arrests, searched 28 locations in Germany and seized 24 inflatable boats, large amounts of nautical equipment, 60 electronic devices, arms, and several thousand euros in cash.

About 900 German police officers in total were involved in the operation, the Belgian federal prosecutor's office said in a separate statement.

Earlier this month, the EU’s Frontex border agency said irregular immigration to the bloc from Western Africa had risen more than 10 times in the year, in January.

Frontex said it expects overall arrivals to grow in 2024 and that halting the movement of people completely is impossible.
