Twelve migrants, including an infant, have died in two separate incidents involving boats travelling from Turkey towards the Greek islands of Lesbos and Samos, prompting investigations into the circumstances of the deaths and the activities of suspected people smugglers.
The incidents occurred on Monday, 19 October, in the northeastern Aegean Sea. Six people died when a speedboat collided with a Greek coastguard vessel near Lesbos, while another six were killed after a separate boat overturned north of Samos.
The deaths coincided with the publication of new figures from the European Border and Coast Guard Agency, Frontex, showing that irregular crossings into the EU fell by almost one-third during the first nine months of 2026.
According to the latest border monitoring figures, approximately 91,000 irregular crossings were detected between January and September, although the eastern Mediterranean remained the busiest migration route into the Union.
Two incidents under investigation
According to information released by the Greek authorities, the first fatal incident occurred near Agrilia on Lesbos when a speedboat carrying migrants struck a coastguard patrol vessel before overturning.
Six people died, while eight survivors were taken to hospital. The authorities subsequently arrested a 37-year-old Turkish national, identifying him as the suspected operator of the migrant boat.
Greece’s Maritime Affairs Minister Vassilis Kikilias said the available evidence indicated that the speedboat had struck the left side of the coastguard vessel. The precise circumstances remain under investigation.
In the second incident, approximately four nautical miles north of Samos, a boat reportedly overturned after making a sudden manoeuvre while being pursued by the coastguard.
Five men and one woman died, while 14 people were rescued. An Iranian national was arrested on suspicion of involvement in migrant smuggling.
The arrests do not establish criminal responsibility, and the circumstances surrounding both incidents remain subject to investigation.
Greek authorities have attributed the dangers of the crossings to trafficking networks operating between Turkey and the Aegean islands. The government has reiterated its policy of pursuing smugglers and restricting unauthorised maritime arrivals.
Fewer crossings, continued fatalities
Frontex recorded approximately 31,800 detections along the eastern Mediterranean route during the first nine months of this year, representing a decline of around 15 per cent compared with the equivalent period in 2025.
Across the European Union’s external borders, the agency reported an even larger reduction, with overall detections down by almost one-third.
The Central Mediterranean route experienced a particularly substantial fall, while the Western Mediterranean recorded an increase, reflecting changes in departure points and migration patterns.
These figures count detected border crossings rather than individual migrants and do not necessarily capture every unauthorised arrival.
The latest data also have to be considered alongside exceptional developments elsewhere on Europe’s borders. In July, large-scale movements through Spain’s Ceuta enclave created additional pressures on Spanish authorities and raised questions about the application of the EU’s new asylum arrangements.
The eastern Mediterranean figures encompass several routes, including crossings from Libya towards Crete, movements through the Aegean islands and arrivals across the land border with Turkey.
Consequently, the total recorded for the wider region should not be interpreted solely as the number of people arriving on the Greek islands.
Greece remains central to European border policy
Greece has occupied a central position in EU migration policy since the 2015–2016 crisis, when hundreds of thousands of people arrived from Turkey, many travelling onwards through the Balkans.
The subsequent EU–Turkey migration arrangements were intended to reduce unauthorised crossings and establish procedures for returning certain migrants who did not qualify for protection.
Athens has also faced persistent criticism from human rights organisations concerning allegations of unlawful returns at sea and land borders. Greek authorities deny operating an unlawful pushback policy and maintain that their border operations respect domestic and international law.
The EU’s Pact on Migration and Asylum, which entered into application in 2026, has introduced common procedures for screening arrivals, processing asylum claims and managing people who do not have permission to remain.
Its implementation has placed greater emphasis on border identification, biometric registration and cooperation between national authorities and Frontex.
However, the two disasters demonstrate the continued risks associated with maritime crossings, even during a period of declining arrivals.
Investigators must now establish precisely how both boats overturned, whether criminal offences were committed and what occurred during the encounters with coastguard vessels.
The findings will be relevant not only to the prosecutions of those arrested, but also to continuing scrutiny of maritime enforcement along one of the European Union’s principal external borders.
