The mayor of Suruc in the Sanliurfa province and three mayors from Mazidagi, Savur and Derik districts in the Mardin province were suspended, Anadolu said.

Ankara accuses the Peoples' Democratic Party (HDP) -- the country's third-largest party -- of links to the Kurdistan Workers' Party (PKK), which has fought a bloody insurgency against the state since 1984.

In recent months, the government has cracked down on the HDP -- the only party in parliament that criticised Turkey's offensive against Kurdish militants in northern Syria in October, branding it an "invasion."

With the latest dismissals, the number of HDP mayors suspended by the government has reached 24.
