A Ukrainian drone attack has destroyed more than 40 Russian planes deep in Russia’s territory, Ukraine’s Security Service said on Sunday, while Moscow pounded Ukraine with missiles and drones just hours before a new round of direct peace talks in Istanbul.

Russian and Ukrainian officials are due to sit down on Monday in the Turkish city of Istanbul for their second round of direct peace talks since 2022, but the two sides are still far apart on how to end the war and the fighting is stepping up.

Since last sitting down with Ukraine to talk peace, Russia has launched four of its five largest drone attacks against the country, killed more than 340 of its civilians and continued to peddle its false narrative about the unprovoked war it has been waging for more than a decade.
