Four Croatian police officers were sent to Greece on Tuesday to help guard the Greek-Turkish land border as part of Frontex's Rapid Border Intervention 2020 mission.
The operation is being launched on Greece's request and in accordance with the European Border and Coast Guard regulation. It starts on 11 March and ends on 6 May this year, and will involve a total of 100 police officers from EU member states.
The Croatian police will stay in Greece until 8 April when they will be replaced by another contingent who will stay in the country until the end of the operation in May. There is a possibility of the operation being extended and the contingent enlarged, the statement said.
Greece is facing an influx of migrants from Turkey after Ankara announced on 29 February that it was opening its borders towards the European Union. Turkey has taken in nearly four million people displaced by the Syrian war.
