Evidence

Multiple independent outlets corroborate the claim, referencing an attack dated August 28, 2026. The Moscow Times reported that a Ukrainian drone attack killed one person and sparked a fire at the Slavneft-Yanos refinery in Yaroslavl, citing Yaroslavl region Governor Mikhail Yevrayev and Ukraine's military, with President Zelensky also confirming the strike. The Kyiv Independent similarly reported that Ukraine's General Staff confirmed the strike on Slavneft-Yanos and that Yevrayev said the attack on the region killed one person and injured 27 others (from falling drone debris hitting a bus), though it noted damage to the refinery itself was 'still being assessed' and could not be independently verified by the outlet. This appears to be part of a pattern of repeated Ukrainian strikes on this same refinery throughout 2026 (also hit in May and August 6), so search results include coverage of multiple separate incidents at the same facility, but the specific claim (one killed, fire sparked, attributed to Ukrainian drones) matches the August 28, 2026 reporting closely. No dedicated Reuters, AFP, Bellingcat, or EUvsDisinfo fact-check specifically addressing this August 28 incident was found in search results.
