Ukrainian drones struck the command post of a Russian Federal Security Service (FSB) counterintelligence unit in Russian-occupied Donetsk on April 22, killing 12 officers and wounding 15 others, according to Robert “Madyar” Brovdi, commander of Ukraine’s Unmanned Systems Forces (USF).
Brovdi said on Telegram that USF operators conducted eight precision strikes at 8:01 a.m. using FP-2 drones, medium-range munitions built by Ukrainian company Fire Point and carrying warheads between 60 and 100 kilograms.

The operation was planned by USF’s Deep Strike Center with specialists from the Azov 1st Corps of the Ukrainian National Guard and executed by the “Ptakhy” (Birds) unit. The strikes also destroyed a forward deployment site, bringing total reported FSB casualties to 27 personnel.
The target was the FSB’s Mobile Operations Directorate (UMD), which Brovdi described as functioning “as special forces” within Russia’s counterintelligence service. “The UMD performs counterintelligence tasks, sabotage, military special operations, creation of agent networks, search and detention of disloyal citizens, physical elimination of opponents, and coordination of pro-Russian militants,” he wrote. He added that inside Ukrainian-controlled territory, the unit carries out terrorism, sabotage, arson, and recruitment.

Videos circulating on social media appeared to show Ukrainian drones striking a multi-story unfinished building in Donetsk. The footage has not been independently verified, and Russia has not publicly commented on the strike.

Brovdi’s forces deployed the same FP-2 platform three weeks earlier, on April 6, when USF aircraft and Security Service of Ukraine (SBU) assets used the system to strike the Russian Navy frigate Admiral Makarov, a Project 11356 vessel capable of launching Kalibr cruise missiles, in the port of Novorossiysk, despite the warship’s air defenses engaging the incoming drones.
