During the open discussion Q&A at the plenary session of the SPIEF event, Russian President Vladimir Putin answered a question about Western plans to deploy F-16 jets to Ukraine.
“Tanks are burning. Among them are the Leopards. They burn. So will the F-16s. There is no doubt,” the Russian President said. If Kiev gets F-16s and they are stationed at air bases in neighboring countries, “we will need to look at how and where we can hit those assets used in combat operations against us,” Putin said. “This is a serious danger of further dragging NATO into this armed conflict.” (http://en.kremlin.ru/events/president/news/71445 )
