Russia’s Deputy Security Council Chairman, Dmitry Medvedev, has issued a stark warning to citizens of European Union countries, declaring that their governments had “unilaterally entered into a war with Russia” amid escalating tensions following a reported Russian drone strike in Romania.

Medvedev’s comments came after top Western leaders condemned what they described as a Russian drone incursion into Romanian territory that injured civilians and heightened fears of a wider confrontation between Russia and NATO allies.

In a statement posted on Friday, May 29, 2026, Medvedev warned European citizens to prepare for worsening instability.

“Citizens of EU countries, You should realize your authorities have unilaterally entered into a war with Russia. So be vigilant and don't be surprised by anything. The peaceful sleep is over. But you know who to ask why!” he wrote.
