Greece's Government says it has finalised plans to build a wall along its northeast border with Turkey, over concerns that migrants may try to stage mass crossings into the European Union country.
Government spokesman Stelios Petsas said that 26km of wall would be added to an existing 10km section of fence in a 63-million-euro project due to be completed by the end of April.
A standoff occurred at the border earlier this year after Turkey said it would no longer prevent migrants trying to reach the EU, and tens of thousands tried to cross into Greece.
The two countries are also at odds over energy rights in the eastern Mediterranean in a dispute that has triggered a dangerous military build-up in the region and fears of conflict.
Four Greek construction companies have been selected to build the new wall and upgrade the existing section of fencing, running along or close to the Evros River, which forms much of the border between the two countries.
