In anticipation of a potential wave of refugees from Afghanistan, Greece has completed the construction of a 40-kilometer fence on its land border with Turkey, according to Reuters.
The new fence complements the previously built 12.5-kilometer cement-wire fence. A modern high-tech monitoring system has also been installed.
Turkey is also considering building a fence, but on the 295-kilometer border with Iran.
The pressure of migrants on the Bulgarian-Turkish border is also increasing.
