Speaking in Brussels on Monday, the EU’s Commissioner for European Neighborhood Policy and Enlargement Negotiations Johannes Hahn was quoted as saying: "It looks at least as if something has been prepared. The lists are available, which indicates it was prepared and to be used at a certain stage."

He was speaking after the failed coup attempt in Turkey on July 15 which claimed more than 200 lives and injured thousands. More than 6,000 suspects have been arrested in connection with the plot, including military figures and judges.

Cavusoglu later tweeted that Hahn "is far from thoroughly comprehending what is going on in Turkey". He added that Turkey’s "primary expectation" from its European allies was their "support [for] the democratic process in Turkey and strong condemnation of the coup attempt."

"Turkey will never compromise on human rights, the rule of law and democracy," Cavusoglu said, adding: "Therefore, no one, including Mr. Hahn, can prejudge the ongoing legal process regarding the bloody coup attempt in Turkey."

The coup-plotters are accused of having links to U.S.-based Fetullah Gulen, who is said to have pursued a long-running campaign against the government through supporters within the Turkish state.

Gulen is the main suspect in two investigations launched into the attempted coup by Istanbul prosecutors, judicial sources told Anadolu Agency on Sunday on condition of anonymity due to restrictions on speaking to the media.

A total of 8,777 personnel were dismissed from their duties, including 30 governors, 52 civil inspectors and 16 legal advisers, Turkey’s interior ministry has said.
