Major General Anton Grunis Killed by Drones in Donetsk Oblast
Ukrainian drone operators targeted and killed Major General Anton Grunis on September 12, 2026, in the temporarily occupied territory of Donetsk Oblast, according to reports from Ukraine’s Unmanned Systems Forces. Robert Brovdi, commander of the Unmanned Systems Forces, stated that the strike was carried out by the Rarog unit, which belongs to the 427th Separate Unmanned Systems Brigade. Brovdi noted that Grunis is the seventh Russian military commander at the brigade, division, or army level confirmed killed by Ukrainian drone units.
Confirmation of the death came from multiple channels. Major General Apti Alaudinov, who serves as deputy chief of the Russian Defense Ministry’s ideological arm and commander of the Akhmat special forces, posted a brief notice on Telegram confirming that Grunis had died in the eastern Donetsk region. He left us as a hero who carried out his sacred duty,
Alaudinov wrote on Telegram, without detailing the date or circumstances.
“As a man with a Hungarian surname, born in Ukraine and using the birds to fight for the motherland, I report loud and clear: General Grunis was eliminated by the USF birds’ champion department of retribution on 12 September 2026 in his night-time lair in the temporarily occupied territory of Donetsk Oblast.”

Disputed Claims Over the Capture of Kostiantynivka
The battlefield loss follows high-profile claims made by Grunis earlier in the year. Following that report, Putin awarded Grunis the Gold Star Hero of Russia medal during a ceremony in late August.
However, Ukrainian officials and international war analysts disputed the territorial claims. According to the U.S.-based Institute for the Study of War, Russian forces infiltrated parts of Kostiantynivka but never fully seized control. Analysts characterized Moscow’s announcement as part of a wider information campaign intended to portray Ukrainian frontlines as collapsing.
Overnight Strikes Hit Energy and Civilian Infrastructure
The developments on the frontlines coincided with a wave of overnight missile and drone attacks across multiple Ukrainian regions. President Volodymyr Zelenskyy reported that civilian and energy infrastructure was targeted in eight regions, including Sumy and Odesa.
In Kyiv, falling debris damaged warehouse facilities and areas near a petrol station, while air strikes injured 18 people. Kyiv Mayor Vitali Klitschko confirmed that 12 people, including two children, were wounded in the capital. In Odesa, a 19-storey apartment building was struck, injuring three people, including a child. Separate strikes in Zaporizhzhia wounded three individuals and ignited a fire at an industrial facility.
These attacks follow a series of transportation and industrial strikes earlier in the week. Ukrainian officials reported that Russian drones struck a passenger bus near Nikopol, killing five people and wounding seven others, while another drone attack targeted a passenger train multiple times in the Mykolaiv region.
Drone Strikes Damage Russian Refineries and Infrastructure
Inside Russia, ongoing Ukrainian drone operations continued to disrupt domestic fuel production. Regional Governor Mikhail Yevrayev confirmed that a Ukrainian drone attack damaged an oil refinery in the city of Yaroslavl, triggering a fire that emergency crews later extinguished. The facility, known as the YANOS plant, is jointly controlled by Rosneft and Gazprom Neft and is located roughly 250 kilometers northeast of Moscow.
Separately, authorities in Russia’s southern Krasnodar region reported an industrial fire caused by falling drone debris. The recent strikes on oil refineries have led to domestic fuel restrictions, with the Russian government extending a ban on diesel exports through the end of October to manage shortages driven by refinery disruptions.
