"Yes, we prepared the list and handed it over to the [Ukrainian Parliament] Verkhovna Rada," Gitlyanskaya said, not specifying what media were included.
Another source in the agency confirmed to RIA Novosti that over 100 Russian media may be deprived of accreditation.
The source noted that news outlets with Russian titles, which had been registered in Ukraine, would not be banned.
On Tuesday, Ukrainian government signed a document stating that the accreditation of Russian journalists at Ukrainian government agencies has been suspended. The Ukrainian parliament voted to pass the legislation last week.
The Russian Foreign Ministry responded that the suspension was a part of the Ukrainian policy to "sanitize" the media space.
