As the front lines froze, and air defenses got better, Russia and Ukraine pivoted away from close bombing runs to standoff attacks.

As Russia launched the attacks, Poland's Armed Forces said on X that it launched "all available forces and assets," which included aircraft being scrambled and ground-based air defense and radar reconnaissance being put on the "highest state of readiness."

Polish and allied NATO aircraft were scrambled in response to a large Russian drone and missile attack launched into Ukraine on Sunday night, the Polish military's Operational Command said in a statement.
