Hackers claim to have leaked online a database of personal information of nearly 50 million Turkish residents, including Turkish President Recep Tayyip Erdogan, his predecessor Abdullah Gul, and Prime Minister Ahmet Davutoglu. The authenticity of the documents was partially verified by the Associated Press on Monday.

“Who would have imagined that backwards ideologies, cronyism and rising religious extremism in Turkey would lead to a crumbling and vulnerable technical infrastructure?” the hackers posted on a site that seems to be hosted by an Icelandic group, which specialises in divulging leaks, using servers in Romania. The downloadable 6.6GB file contains national identification numbers, birth dates, addresses and parents’ names of 49,611,709 individuals.
