Ukraine and Russia have escalated their shadow war of espionage, sabotage, and assassinations, with both countries claiming a growing list of captured agents, intercepted plots, and cross-border attacks.

Ukrainian officials say Russia has fired more than 700 attack and decoy drones at Ukraine overnight. That tops previous nightly barrages for the third time in two weeks.

President Volodymyr Zelenskiy said that Russia launched 597 drones and 26 missiles, killing two people, wounding 20, and damaging civilian infrastructure from Kharkiv and Sumy in the northeast to Lviv, Lutsk, and Chernivtsi in the west.
