Vladimir Putin is stuck in his military campaign against Ukraine and could be preparing for another attack, said Ukrainian President Volodymyr Zelenskyy in an interview with The Guardian.

The Kremlin is currently waging a hybrid war against Europe while testing NATO’s red lines.

Zelenskyy warned that Russia could open a second front against another European country before the war in Ukraine ends.

“I believe so. He can do that. We must forget about the general European scepticism that Putin first wants to occupy Ukraine and then may go somewhere else. He can do both at the same time,” he said.
