A drone attack has caused a fire in the port area of Ust-Luga on the Baltic Sea in northwest Russia with injuring three workers as regional governor Aleksandr Drozdenko said on Wednesday.
Drozdenko wrote on Telegram that a power station was also cut off during the attack. He said 150 drones were shot down over the Leningrad region. The region is home to a major oil refinery and to St Petersburg, the hometown of President Vladimir Putin.
Ust-Luga is a major export outlet for oil, oil products and grain among other goods.
The attack also affected neighbouring countries. Lithuania, Latvia and Estonia warned of a drone threat on Wednesday. Finland adopted temporary partial airspace and maritime restrictions.
Reuters could not immediately confirm the governor's report independently.
