You might want to check the following reports about the mystery excavation that goes on under the protection of Turkish police and special forces for about a year and about which no specific explanation was made by the State officials (other than the Turkish PM's recent explanation that it is an archaeological excavation, cited in the third link)

https://news.sol.org.tr/mysterious-excavation-under-turkish-special-forces-supervision-172720 (a leftist Turkish news portal's report about the event dated July 2017)
https://www.dailysabah.com/turkey/2017/11/01/mystery-surrounding-excavation-in-southern-turkey-continues-to-baffle-locals (Another report that seems to be published today, containing the most specific information about the excavation).
One of the interesting claims about the digging among public people is that it might be involving the Bible of the Apostle Paul, who is historically known to have lived in this specific region. But, there seems to be no concrete finding to support this claim. There are also references to other historical personages such as Daniel and his treasure, etc. What seems to be certain is that, if nothing else, the findings are valued materials to be displayed in a museum. I hope that state officials or any other groups do not steal or hide anything about it.
