"Putin's criminal war is getting closer to our borders," Polish Foreign Minister, Radosław Sikorski, said on Wednesday.

Russia launched another large-scale attack on Ukraine, injuring 15 people, while Ukrainian President Zelensky called for more air defense systems and interceptors to counter the terror, and President Trump warned Russia of tougher sanctions if the attacks don't end.

Russian officials and commentators have shown little indication that Moscow is about to change course under new pressure.

President Donald Trump’s ultimatum to Russia to accept a peace deal in Ukraine within 50 days or face bruising sanctions has given the Kremlin extra time to pursue its summer offensive.

That included a Monday joint statement from Republican Sen. Lindsey Graham and Democratic Sen. Richard Blumenthal calling Trump’s threat of ramped-up economic penalties if Russia doesn’t cut a peace deal in next 50 days “a real executive hammer to drive the parties to the negotiating table.”
