Turkey plans to build an 8.5-kilometer (5.2-mile) wall on its western border where neighbors Greece and Bulgaria have already erected their own fences, Agence France-Presse reported on Wednesday, citing a local governor.
The barrier is aimed at preventing migrants from crossing into EU member states.
Turkey has in the past built walls on its border with Iran and Syria.
“For the first time we will take physical security measures this year on our western border,” Yunus Sezer, the governor of Edirne in northwestern Turkey, told reporters.
The governor said that initially a 8.5-kilometer wall was planned, adding that it could be extended.
Turkey shares a 200-kilometer (120 mile) frontier with Greece, part of which is the Evros (Meriç) River.
In 2012 Greece built two three-meter-high barbed wire barriers along 11 kilometers (seven miles) of its frontier with Turkey, which has previously been mined.
It later tripled the length of the fence, with Prime Minister Kyriakos Mitsotakis vowing to extend it to more than 100 kilometers by 2026.
