Computer hackers have leaked an online database which they say contains the personal information of nearly 50 million Turkish citizens.
The information includes names, national ID numbers, addresses, birth dates and parents' names. It specifically highlights the personal data of President Recep Tayyip Erdogan and Prime Minister Ahmet Davutoglu.
The Associated Press was able to partially verify the information.
The hackers posted a message with the leak: "Who would have imagined that backwards ideologies, cronyism and rising religious extremism in Turkey would lead to a crumbling and vulnerable technical infrastructure?''
The database appears to be have been posted using servers in Romania.
