Ukraine on Sunday launched one of its broadest assaults of the war against air bases inside Russia, a coordinated operation that targeted sites from eastern Siberia to Russia’s western border and that left several Russian aircraft in flames.
The Ukrainian drone attacks on Russian airfields came as Kyiv suffered a damaging blow of its own on Sunday, with Russia striking a Ukrainian military training base and killing at least 12 soldiers.
The day’s violence showed that the fighting between the two adversaries was only escalating even as they were expected to sit down for another round of cease-fire negotiations on Monday in Istanbul. Russian forces have quickened the pace of their advances in Ukraine and bombarded Ukrainian cities, as Ukrainian leaders accuse Russia of stalling for time in the peace talks and Moscow pushes for a breakthrough in the conflict after more than three years.
