ATHENS—Greece’s border forces are on alert to avoid a repeat of the mass arrivals of migrants that the country experienced in 2015, the government’s spokesman said on Thursday, following the return of the Taliban to power in Afghanistan.

Greece was on the frontline of Europe’s migration crisis in 2015, when nearly one million people fleeing conflicts in Syria, Iraq and Afghanistan landed on its islands.
