Greece has increased its fence border in fears of repeating the 2015 refugee crisis.

According to reports it has completed a 40-kilometre fence on its border 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.

A statement from the office of Turkish President Tayyip Erdogan says Afghanistan and Iran - a key route for Afghans into Turkey - should be supported or a new migration wave was “inevitable,".
