Two explosions in the early hours of 30 May near Desantnaya Bay in Russia’s Vladivostok were part of a planned operation by Ukraine’s military intelligence agency (HUR), according to Ukrainian outlets RBC-Ukraine and UNIAN.
Sources say the blasts targeted the 47th Separate Air Assault Battalion of Russia’s 155th Guards Naval Infantry Brigade (Unit No. 30926). One explosion reportedly struck a checkpoint, the other hit an area housing personnel and commanders.
This brigade has been actively involved in combat against Ukraine, including documented deployments in Mariupol, Vuhledar, and Kursk Oblast.

According to the same sources, the attack caused injuries and material damage.
“Personnel, military equipment, and special assets were hit,” the reports quoted unnamed intelligence sources as saying.

Russian officials: Gas leak caused the blasts
Russian authorities confirmed two explosions but denied any casualties or damage. The Anti-Terrorism Commission of Primorsky Krai attributed the incident to the ignition of gas cylinders.
Emergency services cordoned off the area, and traffic between Shamora Bay and the village of Shchitovaya was partially restricted.
“The threat has been neutralized,” officials stated.
Tightened security and conflicting accounts
Local media and Telegram channels, including VChK-OGPU and Vladivostok1.ru, reported heavy police and military presence in the area. Roads were blocked, vehicles inspected, and helicopters were seen flying before the blasts.
Witnesses described the removal of large, tarp-covered objects—possibly military vehicles—under guard. The Telegram channel The True Story reported that the location is used for loading and unloading military equipment for naval deployment.
According to Radio Svoboda, Desantnaya Bay may also house a training ground for the Pacific Fleet’s naval infantry, which has taken part in combat operations against Ukraine.
