A man killed by a bomb in occupied Sevastopol was likely a Ukrainian naval officer who had switched sides to Russia. The Insider has identified the victim of a 13 August explosion in Sevastopol as Robert Shageev, a former Ukrainian Navy officer, the journalists reported.

The killing reportedly struck a man whose career embodied the choice between homeland and working with enemy forces during the annexation of Crimea in 2014.

Robert Shageev commanded the Ukrainian submarine Zaporizhzhia, which was blockaded in Sevastopol's Striletska Bay when Russian forces seized the peninsula, and he deserted the Ukrainian Navy to serve in the Russian fleet, The Insider writes.

The bombing

The explosion was likely a targeted attack. An improvised bomb was placed in a bin next to a bench on Stoletova Avenue in Sevastopol and detonated as a man passed by on the afternoon of 13 August, and he died of his injuries, according to Telegram channels.

Russian authorities confirmed a death without naming Shageev. The FSB confirmed only that a soldier of Russia's Defense Ministry was killed, according to Russian state media. That Shageev was the victim was first claimed by pro-Russian bloggers before The Insider's identification, and the claim has not been officially confirmed.

A suspect was detained

Russian authorities said they detained a suspect. The FSB reported detaining a suspected woman, and a court in Sevastopol later said she had been sent to pre-trial detention, without disclosing her identity, according to The Insider.

Meanwhile, pro-Russian Telegram channels and a Crimean informant claim the detained woman is a 32-year-old. Crimean informer Alexander Talipov, as well as Telegram channels linked to Russian security forces, claim that the detainee is 32-year-old Margarita Reut. Last year, she was fined for "discrediting the Russian army".

According to the New York Post, the Russian citizen appeared on escort websites and also worked as a biologist, producing vaginal suppositories with a floral scent.

The identification comes from Russian sources and has not been verified. Ukraine has not commented on the killing, and no party has claimed responsibility.

Targeted killings and sabotage have recurred in occupied Crimea and Russia through the war. Collaborators, occupation officials, and defectors have been killed in bombings and shootings, some claimed by Ukrainian intelligence or partisans, many never definitively attributed.

Ukraine’s Navy said its forces struck the launch positions and deployment site of a Russian Bastion coastal missile system in occupied Crimea overnight on 16 August, reportedly inflicting significant losses in equipment and personnel.

Russia has regularly used Crimea as a launch platform for strikes against Ukraine, making its missile systems there a priority target for Ukrainian forces seeking to reduce Russia’s ability to attack Ukrainian territory.

The Navy said the final Russian losses were still being assessed and did not provide details on the weapons or personnel destroyed.

Bastion systems used to strike Ukraine

The Bastion is a costly and scarce Russian coastal missile system that can launch P-800 Oniks cruise missiles. Russia has used Oniks missiles launched from occupied Crimea to attack targets across southern and other regions of Ukraine.

Oniks is a supersonic anti-ship cruise missile that Russia has adapted for strikes against ground targets in Ukraine, including Odesa Oblast. The missile can travel at more than 3,000 km/h, making it difficult for air defenses to intercept. Its standard range is about 300 kilometers, while upgraded variants can reportedly reach up to 800 kilometers and carry a 300-kilogram warhead. Russia launches ground attacks with Oniks from mobile Bastion systems based in occupied Crimea.

The Navy also said Russia uses Bastion systems to launch Zircon hypersonic missiles against Ukraine.

The Zircon is a newer hypersonic cruise missile designed to reach speeds of roughly Mach 5–9. Russia has used it against Ukrainian cities, including Kyiv, with launches previously reported from Bastion systems in occupied Crimea. Its officially claimed range exceeds 1,000 kilometers, although analysts question that figure; Ukrainian analysts have estimated a lower effective range.

Bastion launchers in Crimea are a particularly important target for Ukraine: they give Russia a mobile platform for striking targets across southern Ukraine and, with Zircon, deep into the country. Ukraine’s air defenses have struggled to intercept these missiles, making strikes on the launchers an important way to reduce the threat before the missiles are fired.

The Ukrainian Navy said the strike was part of ongoing efforts to reduce Russia’s combat potential in the Black Sea region.

Several Ukrainian strikes recorded overnight

The Crimea strike came amid a broader wave of Ukrainian attacks on Russian military, industrial, and logistics targets overnight on 16 August.

Ukraine’s General Staff reported a strike on the Kamensky Combine in Russia’s Rostov Oblast, where a fire was recorded. The plant produces solid rocket fuel for Russia’s Uragan, Smerch, and Tornado-S multiple-launch rocket systems, as well as components for other missile and aviation weapons.

In Moscow Oblast, a Ukrainian drone struck a 250,000-square-meter Wildberries warehouse in Koledino, while another fire was reported at the Severnoye Domodedovo logistics complex. Ukraine’s Defense Ministry later confirmed the Wildberries facility had been put out of operation, saying it was the retailer’s largest warehouse by area.

The General Staff also confirmed the results of two earlier strikes. It said the ZapSibNeftekhim petrochemical complex in Tobolsk was shut down after its central gas-fractionation unit was struck on 10 August, while an 11 August strike damaged several processing units at the Orsknaftaorgsyntez refinery in Orenburg Oblast.

The strikes show the expanding reach of Ukraine’s campaign against the military and industrial infrastructure supporting Russia’s war, from missile systems and rocket-fuel production to oil, petrochemical, and logistics facilities.
