Despite the changes in warfare, Russian forces retain the ascendancy and are making slow but steady advances in the east and north of Ukraine. Russia has also caught up in UAV technology after falling behind early in the war, according to military analysts, and like its enemy is churning out drones domestically at a rate of millions a year.

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

Russian troops struck Dnipro and the Dnipropetrovsk region with drones. Fires broke out in the city, businesses were damaged, and there were casualties among civilians, according to the head of the Dnipropetrovsk Regional Military Administration,

Three Ukrainians were killed in the southeastern Dnipropetrovsk region, where Russia captured a first village this week after a months-long incursion. In the neighboring Zaporizhzhia region — the site of a nuclear plant — two civilians were killed in the attacks, Gov. Ivan Fedorov said.

Officials say a Russian drone barrage has targeted the center of Kharkiv, injuring nine people and damaging a maternity hospital in Ukraine’s second-largest city

Russia and Ukraine struck each other with hundreds of drones on Sunday, throwing Russian air travel in disarray, shortly after Ukrainian President Volodymyr Zelenskyy announced deals with Western partners that would allow Kyiv to scale up drone production.
