This now includes not just an ongoing militarized response on the Greek side to keep thousands from crossing illegally, but reportedly now erecting huge concrete blocks at key land crossings.

The completely shuttered border crossings with Turkey are beginning to resemble war zones akin to WWI trenches and fortifications:

"Greece on Friday placed 5-foot concrete blocks at its Kastanies border crossing with Turkey to stop the entry of asylum seekers," Turkey's Anadolu Agency reports.

For weeks since Erdogan said he had in an act of retribution aimed at uncooperative EU states 'opened the gates' on hundreds of thousands of Syrian refugees from Idlib seeking entry into Europe, the border situation has seen running battles between throngs of migrants and Greek border guards.
