A Ukrainian official reported on Sunday that Russia conducted its most extensive aerial assault overnight since the conflict began.

According to Ukraine’s air force, Moscow deployed 537 aerial weapons against Ukraine, comprising 477 drones and decoys along with 60 missiles. Of these, 249 were intercepted, while 226 were unaccounted for, believed to have been neutralized through electronic jamming.

Yuriy Ihnat, head of communications for Ukraine’s air force, informed The Associated Press that this attack represented “the most massive airstrike” on Ukraine since Russia’s full-scale invasion commenced in February 2022, considering both drones and multiple missile types.

Numerous regions were hit, including parts of western Ukraine situated a significant distance from the conflict’s front lines.

Poland’s air force stated that Poland and its allied nations launched aircraft to safeguard Polish airspace.

Governor Oleksandr Prokudin reported one fatality in the Kherson region, while Governor Oleh Syniehubov of the Kharkiv region confirmed another death after a drone struck a vehicle. In Cherkasy, regional Governor Ihor Taburets stated that six individuals, including a child, sustained injuries.

A drone attack in Drohobych, located in the far-western Lviv region, ignited a substantial fire at an industrial complex and caused power outages in sections of the city.

Ukraine’s air force confirmed that one of its Western-supplied F-16 warplanes crashed, killing the pilot, after being damaged while engaging aerial threats.

These recent assaults occurred following Russian President’s statement on Friday that Moscow is prepared for a new round of direct peace negotiations in Istanbul aimed at resolving the conflict.

With no resolution apparent, international peace initiatives facilitated by the U.S. have yet to achieve any significant progress. Two recent, brief rounds of discussions between Russian and Ukrainian delegations in Istanbul concluded without advancing toward an agreement.
