Greece has stepped up efforts to patrol its borders by completing a 40-km fence on its boundary with Turkey and installed a new surveillance system to stop possible asylum seekers from trying to reach Europe following the Taliban's takeover of Afghanistan.
The Afghanistan crisis had created "possibilities for migrant flows," Citizens' Protection Minister Michalis Chrisochoidis said after visiting the region of Evros on Friday with the defence minister and the head of the armed forces
He added “We support the democratic rights and freedoms of people, but we cannot allow the instrumentalization of migrant flows that could possibly occur."
The Taliban's rapid takeover has fuelled fears in Europe of a repeat of the 2015 refugee crisis, when nearly a million people fleeing war and poverty crossed to Greece from Turkey before travelling north to wealthier states.
Greek Prime Minister Kyriakos Mitsotakis and Turkish President Tayyip Erdogan discussed the issue of Afghanistan in a phone conversation on Friday, with Erdogan saying Afghanistan and Iran - a key route for Afghans into Turkey - should be supported or a new migration wave was "inevitable," a statement from his office said.
Greece has hardened its migration policy in recent months by fencing off its migrant camps.
It has in the recent past stopped people entering its waters, though it denies widely reported allegations of so-called "pushbacks."
