Ukrainian drones sparked a fire at Russia's Ust-Luga port Friday, the Baltic Sea's top oil export terminal and the second such strike since July.

Ust-Luga is one of Russia's largest ports on the Baltic Sea and home to an oil terminal that serves as a major hub for the export of crude oil and petroleum products.

A fire was reported at the port of Ust-Luga in Russia's Leningrad Oblast on the night of 13-14 August following a drone attack.
