Ukrainian prosecutors have formally accused a captured Russian marine of executing a Ukrainian unit commander near Pokrovsk, the Donetsk Oblast Prosecutor’s Office said on 20 August. Investigators allege he took the 34-year-old captive to a forest belt after an interrogation and shot him in the back of the head on his superior’s order.

The case comes as Ukraine steps up efforts to prosecute Russian troops accused of executing or abusing Ukrainian POWs. Ukrainian investigators and UN monitors have documented a growing pattern since 2024 of Russian forces executing Ukrainian troops after capture.

The alleged gunman is now in Ukrainian custody, opening the way for an in-person trial. Russian troops also shot dead a second Ukrainian prisoner, prosecutors said.

Russian assault units had been trying to seize Shakhove on the Pokrovsk front since May 2025, according to the prosecutor’s office. On 10 October 2025, a small Russian infantry group entered the village’s outskirts and captured two Ukrainian service members, including the commander, the office alleges.

After the interrogation, the suspect took the commander to a forest belt and killed him with an automatic rifle, prosecutors said. The other Ukrainian prisoner was also shot dead. The statement names neither victim.

Investigators identified the suspect as a 34-year-old native of Russia’s Krasnoyarsk Krai who used the call sign “Tai” and served as a rifleman in the 336th Guards Naval Infantry Brigade.

Ukrainian forces later captured him during fighting in the same sector, according to prosecutors. The office did not say when he was taken prisoner.

Prosecutors formally accused him of cruel treatment of prisoners of war resulting in death, a war crime under Ukrainian law.

Ukraine’s other cases against captured Russian soldiers

Ukraine has previously brought cases against other captured Russian soldiers over POW executions. A Zaporizhzhia court sentenced Dmitry Kurashov to life imprisonment in November 2025—the first time Ukraine convicted a Russian soldier of executing a surrendered Ukrainian POW.

In a separate case, the Security Service of Ukraine charged Sergey Tuzhilov over the execution of one bound Ukrainian POW and his alleged role in killing two others near Vovchansk in June 2024.

Russian UN Ambassador Vasily Nebenzya denied reports that Moscow could launch another mass mobilization after September’s parliamentary elections, saying none was planned or expected “as far as I know,” The Moscow Times reported

Russia has avoided another draft since its 2022 mobilization triggered protests and an exodus, relying instead on contract soldiers. Ukraine says those recruits no longer replace battlefield losses, and Moscow may mobilize several hundred thousand people after the elections. That could replenish its forces and support new offensives, although Ukrainian intelligence sees no preparations now.

Nebenzya’s remarks followed a question about more than 20,000 people crossing Russia’s Verkhny Lars border checkpoint into Georgia in one day amid fears of post-election mobilization, Meduza reported.

His comments extend a series of Russian denials. Deputy Security Council Chairman Dmitry Medvedev dismissed reports of another mobilization as “nonsense” in late July. The State Duma’s defense committee said a mass compulsory call-up was not under consideration because the army was recruiting contract soldiers, The Moscow Times reported.

Russia has avoided another mass draft since its September 2022 mobilization triggered protests and an exodus. Officials had also denied that mobilization was planned shortly before President Vladimir Putin announced it, Meduza noted.

Russian government seeks new wartime penalties

Moscow is separately seeking penalties for people and companies that ignore mobilization and military-supply orders issued by regional authorities. The bill would not itself order a new call-up.

The government submitted it to the State Duma, the lower house of Russia’s parliament, on 20 August, The Moscow Times reported. Companies could face fines of up to 1 million rubles or suspension for up to 90 days.

Russian law already punishes such defiance in areas under martial law but imposes no nationwide penalty elsewhere in Russia, according to the bill. Its authors said a “significant number” of violations had been recorded.

Ukraine says a new draft could provide troops for a northern offensive

President Volodymyr Zelenskyy said on 11 August, citing Ukrainian military intelligence, that Russia planned to mobilize several hundred thousand people after the elections and roughly the same number in 2027.

HUR, Ukraine’s military intelligence agency, later assessed that a post-election mobilization could enable Russia to build a strike force for a northern offensive by February 2027. Its deputy chief, Vadym Skibitskyi, stressed, however, that the agency currently sees no evidence that such preparations have begun.

Ukraine is investigating officers who cheated soldiers and misused defense money. The State Bureau of Investigation (DBR) has launched a large operation, "Justice for Soldiers", on 20 August, checking cases of illegal payments to soldiers, the use of soldiers for private work, and corruption, together with the General Staff, the DBR reported.

The operation is part of Ukraine's effort to control its own military and defense spending during the war. Across 21 criminal proceedings, investigators planned 72 searches in various regions and prepared to notify 22 people of suspicion, as part of an internal accountability push.

The biggest category is illegal payments

Most of the cases concern money wrongly paid to soldiers. Twelve proceedings deal with the illegal calculation and receipt of payments by soldiers, with 58 searches conducted and suspicions planned against 20 people, the DBR said.

The bureau has already closed some cases. It finished investigating four more proceedings on illegal payments and plans to send indictments against 16 people to court.

Some commanders used soldiers as private labor

A separate strand targets the misuse of soldiers themselves. Five searches are being conducted in a case involving the illegal use of military labor, in which subordinates, instead of performing military duties, were used for construction, household, and other work in commanders' private interests, the DBR said.

That practice diverts soldiers from the war. Using troops as personal labor for officers takes fighters away from their duties and abuses the command relationship, the kind of misconduct the operation is meant to root out.

The bureau frames it as accountability

The remaining searches target corruption. Nine searches are underway in a case of corruption abuses, with suspicions prepared against two people, and the operation is being conducted with the General Staff and under the procedural guidance of the Prosecutor General's Office.
