Croatian authorities said the group was discovered near the village of Donje Prilisce, about 70 kilometers southwest of the capital Zagreb. Thirteen additional migrants were taken into custody and transferred to a detention facility.

Police said the individuals were allegedly transported by truck and abandoned near the border by a suspected smuggler who fled the scene. The cause of death was not immediately confirmed, and an investigation is ongoing.

Croatia, a member of the European Union, is a key transit point along the Balkan migration route used by people attempting to reach Western Europe.According to the Frontex, more than 12,500 migrants used the route in 2025.

The International Organization for Migration has reported that over 400 people have died or gone missing along this corridor since 2014.Recent incidents highlight the risks faced by migrants on the route.

Earlier this year, a migrant died after a boat capsized while crossing from Bosnia into Croatia, while last month authorities rescued 30 people stranded in a marsh near the same border.

Under the agreement, France will significantly expand its coastal security presence, increasing the number of officers tackling irregular migration by more than 50% to reach 1,400 by 2029. The funding from United Kingdom will be partly conditional, with nearly a quarter tied to performance benchmarks assessing the effectiveness of French actions.

The deal follows months of negotiations between United Kingdom and France over renewing the Sandhurst Treaty, which governs British financial contributions toward efforts to prevent migrants from departing French shores.

British authorities have long argued that France needed to do more to stop departures, as crossings by small boats have become a politically sensitive issue in the UK. London had insisted on tighter oversight and conditions on how funds are deployed before agreeing to renew the framework, first signed in 2018 and extended in 2023.

According to the roadmap, funding allocations could be redirected if joint annual assessments determine that the measures fail to deliver sufficient results. French authorities also plan to deploy additional surveillance tools, including drones, helicopters and digital monitoring systems, to reduce departures, particularly those involving so-called “taxi boats.”

Under international maritime law, authorities are limited in their ability to intervene once vessels have left shore, focusing primarily on rescue operations to prevent loss of life.

Official British data shows that 41,472 people reached the UK via irregular small-boat crossings in 2025, the second-highest annual figure since such journeys were first recorded in 2018.

At least 29 migrants died attempting the crossing that year, according to figures compiled from French and British sources.
