MOSCOW, April 3. /TASS/. Russia will not be "flexible" toward EU nations that provide their airspace to the Ukrainian army for strikes on its territory, Russian Federation Council Speaker Valentina Matviyenko told Olga Skabeyeva, one of Russian TV's most prominent talkshow hosts.

"We are getting new terrorist attacks, attacks on our energy infrastructure, civilian facilities and people. And we will not be flexible with everyone, we will not succumb to the threats of the Europeans or anyone else. We have issued very harsh warnings to these countries," she said.

Matviyenko said that Lithuania has already said it had denied Ukraine permission to fly its drones.

"That is, we shook them up. And they realized that if they continued, they would be our legitimate targets, because Russia was being attacked from their territory. They understood that. I think they're going to crawl away now. They won't say it out loud, but they'll crawl away," she added.
