In October, the number of detections of illegal border crossings on Europe’s main migratory routes fell 17 pct from the previous month to around 16,800 due to a drop in arrivals on the Greek islands in the eastern Aegean. The total on all European migratory routes for the first 10 months of 2019 was 16 pct lower at 107,900, a Frontex report said on Wednesday.

The burst of migratory flows in the Aegean with boats crowded sailing off from the Turkish coast and landing on the Greek islands has led the government to take measures to better monitor maritime space in the Aegean in order to prevent the arrival of refugees and migrants.

Migrant flows from Turkey to the islands of the eastern Aegean continued unabated this week, with 694 people arriving on the shores of Lesvos, Samos and Chios between early Monday morning and Tuesday afternoon.
