Ukraine has intensified its assault on Russian energy infrastructure, striking critical targets such as three shadow fleet tankers and a missile carrier.
"One more Russian carrier of Kalibr missiles is out of action," noted President Zelensky, as he announced the successful strikes on the Primorsk port.
The attacks come amid a surge in violence, with both sides engaging in relentless drone warfare. Reports indicate that at least
eight people have died due to the violence, including casualties in Russia. The governor of the Leningrad region confirmed a fire at Primorsk following the Ukrainian strikes, aggravating tensions in the ongoing conflict.
Zelensky emphasized the necessity of these operations, stating,
"If Moscow does not halt its invasion, we will escalate our strikes on energy sites." The implications of these strikes are significant as they target vessels that have been key in transporting oil to evade Western sanctions and price caps. According to sources, Ukrainian forces reportedly inflicted considerable damage, including the destruction of military facilities and oil port infrastructure.
As the conflict escalates, the situation remains precarious, with Zelensky's government promising a decisive response to any threats posed by Russian aggressions.
