Yurii Ihnat, a spokesperson for the Command of the Ukrainian Air Force, said this at a briefing at the Ukraine - Ukrinform Media Center.
"They have deployed Iskanders and S-400s on Belarusian territory, allegedly for protection of the airspace of Belarus," he said.
Ihnat noted that Russia now does not need S-300 anti-aircraft missiles to protect the airspace, so they are being moved from Belarus to Donbas.
"They use them as ballistic missiles - that is, they fly on a ballistic trajectory for up to 150 kilometers. They are the manufacturers of these missiles, so they have a lot of them. They can afford to 'dispose' of them in this way, because they have a large range of air defense systems, so they don't really need S-300s. They needed to transfer these missiles to Donbas to strike not only the infrastructure of the front-line cities, but also the positions of our troops. We don't sit and watch - the Armed Forces are doing everything to destroy them as efficiently as possible," Ihnat said.
Earlier reports said that the Ukrainian Armed Forces killed about 84,600 Russian soldiers from February 24 to November 21.
