The Polish Prime Minister Donald Tusk pointed out on Friday that Europe is now in a “pre-war period” for which it is unprepared, and warned that a Ukrainian defeat by Russia would embolden Vladimir Putin.

“I know it sounds devastating, especially for the people of the younger generation, but we must mentally get used to the arrival of a new era. Of the pre-war era”, said Task characteristically in his speech to foreign journalists.

“I don’t want to scare anyone, but war is no longer a concept from the past. It’s real, and it started two years ago. We are living in the most critical moment since the end of World War II … literally any scenario is possible,” he noted.

His warning comes as Russia unleashed overnight another large-scale attack to Ukraine’s energy infrastructure with a massive barrage of drones and airstrikes that hit areas across the country, Kiev officials announced.

Russian attacks pushed Poland to raise its own warplanes immediately to protect its airspace from any collateral strikes by drones, missiles or bombers. Last week, Warsaw demanded an explanation from Moscow after one of its missiles briefly invaded Polish airspace during a major missile attack in Ukraine, prompting the NATO member to ground F-16 fighter jets.

The Romanian Ministry of Defense also announced that an investigation has been launched after debris that appears to have come from a drone was found on its territory Thursday night in an agricultural area of ​​Braila County, near the border with Ukraine.
