An official from Ukraine's Interior Ministry who wanted to remain anonymous told Anadolu Agency that intensive clashes had taken place in the region.
The official said Russia intended to seize the facility and bring its own planes there and launch a more intense airstrike on the capital, Kyiv.
The Russian war against Ukraine, which started on Feb. 24, has been met with international outrage, with the European Union, US and the UK among others implementing tough financial sanctions on Moscow.
