A significant fire has broken out at a natural gas terminal in the Russian port of Ust-Luga, located in the Gulf of Finland in the Baltic Sea, near the Estonian border.

The facility, which processes liquefied gas into jet fuel, heating oil, and other petroleum products, is a crucial part of Russia's export infrastructure.

No casualties have been reported as all personnel have been evacuated.

The cause of the fire remains unclear, but there are unconfirmed reports of drone activity in the area prior to the incident.
