Leningrad Region Governor Alexander Drozdenko said multiple drones struck
Ust-Luga port on the Baltic coast, one of Russia's largest oil export hubs,
causing a fire and wounding three workers. He said a substation at the port has
gone offline and preliminary tallies show air defenses shot down 150 drones
overnight; it is unclear whether oil loading operations were affected. Ust-Luga
handles Russian crude and refined product exports; late-March Ukrainian strikes
previously damaged port infrastructure and halted loadings from March 25 to
early April, and past interruptions at Ust-Luga and nearby Primorsk prompted
refiners to seek alternative export routes.
