Ukraine Strikes Russia's Primorsk Port and NORSI Refinery, Inflicting Major Damage
Key Takeaways
- Drones struck Primorsk port on Russia's Baltic coast, causing damage and fires.
- NORSI refinery in Kstovo, Nizhny Novgorod region, was hit, triggering a large fire.
- Russian authorities acknowledged damage at both sites and intercepted multiple Ukrainian drones.
Coordinated Strikes on Key Energy Hubs
Ukrainian drone forces launched coordinated strikes on two of Russia's most vital oil infrastructure sites farther inside Russian territory than any previous strikes.
Ukrainian drone forces commander Robert Brovdi confirmed the strikes on his Telegram channel.

Video footage showed intense air defense activity and fires at both locations.
Primorsk can handle approximately one million barrels per day.
The NORSI refinery can process about 320,000 barrels a day.
Damage and Environmental Impact
Governor Drozdenko initially reported an oil pipeline damaged but later retracted.
A fuel reservoir was hit and leaked.
In Nizhny Novgorod, a fire at the NORSI refinery was confirmed after two facilities were hit.
Residences were damaged causing power outages across two towns.
No injuries were reported.
Strategic Pressure on Russian War Funding
The attacks align with a deliberate Ukrainian strategy to disrupt oil export routes and refining capacity.
“Ukrainian drones have struck Russia’s Baltic Sea port of Primorsk and the NORSI oil refinery in the central Nizhny Novgorod region, according to Ukrainian drone forces commander Robert Brovdi”
The Institute for the Study of War observed a dozen distinct strikes from March 22 to April 5.
Il Giornale described Ukraine's approach as damaging Russia where it hurts most: in the wallet.
Satellite images showed Primorsk had already lost at least 40 percent of its storage capacity in previous attacks.
Continued pressure could prolong export disruption.
Mixed Russian Responses and Increasing Risks
Russian milbloggers offered muted responses.
The Guardian noted heightened diplomatic efforts as the Ukraine war entered its fifth year.

The cumulative economic impact includes rising European natural gas prices.
The risk of unintended consequences grows with each new strike.
