Galina Danilchenko, the newly installed mayor in Russian-occupied Melitopol, said in a televised video Sunday that "Russian TV channels" would begin broadcasting in the region.
Danilchenko claimed there was "a great deficit of trustworthy information being circulated," as reasoning for the broadcasting decision.
Her televised address was posted on social media afterwards by pro-Russian Telegram channels and by the Ukrainian-controlled Zaporozhye regional administration.
Danilchenko was installed as mayor after elected mayor Ivan Fedorov was detained by armed men on Friday.
After he was detained, the prosecutor's office for the Russian-backed separatist region of Luhansk accused Fedorov of terrorism offenses.
Ukrainian President Volodymyr Zelensky demanded his immediate release, saying the "abduction" was a "crime against democracy."
