Turkey replaced party mayors of the southeastern cities of Diyarbakir, Mardin and Van provinces - Adnan Selcuk Mizrakli, Ahmet Turk and Bedia Ozgokce Ertan respectively on Monday over terrorism-related investigations, appointing the state governors in those provinces in their place, the Interior Ministry said, ONA reports citing Yeni Shafak.
The three mayors were accused of various crimes including membership of a terrorist organisation and spreading terrorist group propaganda, the ministry said in a statement.
Turkey dismissed dozens of mayors in the country's southeast in 2016 over suspected links to the Kurdistan Workers Party (PKK) terror group, replacing them with state administrators.
Ahead of local elections in March, President Tayyip Erdogan warned that mayors from the Peoples' Democratic Party (HDP) could again be dismissed if they, like their predecessors, are deemed to have ties to terrorists.
Erdoğan frequently says the HDP has links to the PKK, which is designated a terrorist group by Turkey, the European Union and United States.
The PKK launched an insurgency in 1984. More than 40,000 people have been killed in the conflict.
