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.

Major General Valery Plokhotnyuk was buried in Moscow on 5 August 2026, four days after he reportedly died in a bombing at an Italian restaurant. Security was heavy at the funeral. The ceremony at Troyekurovskoye Cemetery reportedly took place behind roadblocks, metal detectors, and buses carrying Russian National Guard troops.

If he died in the blast, Plokhotnyuk would be at least the fourth senior Russian general killed near Moscow since December 2024. The earlier targets held senior roles in Russia’s war against Ukraine. Moscow has blamed Kyiv for others without presenting public proof. Unlike the three earlier generals, however, independent reporting has not established that Plokhotnyuk himself was the intended target. Responsibility for several of the killings remains disputed or unconfirmed.

The Russian news site Mediazona verified through state registries that Plokhotnyuk died on 1 August 2026, the day of the Moscow bombing. His business partner later confirmed the death after speaking with the general’s father.

Russian officials have not confirmed that Plokhotnyuk died in the blast.

Plokhotnyuk previously commanded Russian troops in Transnistria, a Russian-backed breakaway strip of Moldova. In 2022, he was serving as chief of staff of Russia's 49th Combined Arms Army. Its units attacked southern Ukraine through Kherson and Zaporizhzhia oblasts.

A bomb was brought to the restaurant disguised as a gift

The device that killed Plokhotnyuk exploded at the entrance to Moscow’s Balzi Rossi restaurant on the evening of 1 August. Five people died, and at least 19 suffered injuries.

A woman tried to carry the device inside as a gift but was stopped by a security guard, according to accounts compiled by Sistema, RFE/RL’s Russian investigative unit. The bomb then reportedly detonated remotely.

The woman and the guard both died. Investigators have not said whether she knew that the package contained explosives.

Sistema found several signs that the closed restaurant was hosting a belated 55th-birthday celebration for Colonel General Aleksandr Chaiko, appointed head of Russia’s Aerospace Forces in May 2026.

Footage taken before the blast reportedly showed a backdrop reading “Alexander 55.” State registries confirmed that Chaiko’s son-in-law, Daniil Peredriy, died that day. Chaiko’s daughter, Maria, and another relative reportedly suffered injuries.

The presence of several Chaiko relatives indicates that the event was held for him. However, independent reporting has not established whether he was inside when the bomb exploded. Ukraine has not claimed responsibility.

The EU sanctioned Chaiko in March 2026. It identified him as the senior Russian commander on the ground when Russian forces entered Bucha in February 2022. Hundreds of civilians were killed during Russia’s occupation of the Kyiv suburb.

Far from the front, Russia’s generals keep coming under attack

Before Plokhotnyuk’s reported death, bombings had killed at least three senior Russian generals in Moscow and its surrounding region since December 2024.

A bomb hidden in an electric scooter killed chemical warfare commander Igor Kirillov outside his apartment. An SBU source told Reuters that Ukraine organized the operation.

A car bomb later killed General Staff officer Yaroslav Moskalyk near Moscow. Zelenskyy subsequently mentioned an intelligence briefing on the “elimination” of Russian commanders without naming Moskalyk. Kyiv never formally claimed the bombing.

Another vehicle blast killed military planner Fanil Sarvarov in December 2025. Russian investigators considered possible Ukrainian involvement, while Kyiv remained silent.

No public evidence has established who organized the Balzi Rossi bombing.
