The Ukrainian monitoring channel Exilenova Plus said the port, located near Russia's border with Estonia, caught fire and that explosions broke out at the site. Drones also moved across other Russian regions overnight. The channel reported that a residential building was damaged in Smolensk Oblast amid the attack and that air defenses were engaged in the city of Tver. In the Adygea Republic, explosions were heard, and Exilenova Plus reported a fire on the roof of a residential building after electronic warfare systems were allegedly enabled.
Ust-Luga has been sanctioned by the European Union, Canada, the United Kingdom, the United States and Switzerland over its role in Russia's war against Ukraine. The European Commission's Directorate-General for Enlargement and Eastern Neighbourhood has said Ust-Luga is one of Russia's ports "used to transport Russian crude oil by using the shadow fleet and other irregular and high-risk shipping practices." The shadow fleet aims to circumvent pre-existing sanctions, often shipping oil on vessels with false flags or foreign registration. French President Emmanuel Macron said the French Navy intercepted and boarded a tanker suspected of flying under a false flag as part of the shadow fleet on Oct. 12.
The reported strike is not the first time Ukrainian forces have targeted infrastructure at the port. On Sept. 1, Ukrainian drones hit the Novatek-Ust-Luga complex, damaging key components of an oil-processing unit and other technological equipment and causing a large fire, Ukraine's military intelligence agency confirmed.
