Ukrainian officials reported Russian attacks on critical infrastructure in the west of Ukraine, bordering Poland.

KYIV, Ukraine (AP) — Waves of drones and missiles targeted Kyiv overnight in the largest aerial assault since Russia’s invasion of Ukraine began more than three years ago, officials said Friday, amid a renewed Russian push to capture more of its neighbor’s land.

Russia launched 537 drones and missiles into Ukraine overnight into Sunday morning, according to Ukraine's air force, with a Ukrainian F-16 fighter jet and its pilot also reported lost during efforts to repel the attack.
