Ukrainian drones struck a command post of the Russian Federal Security Service (FSB) in occupied Donetsk on April 22, killing 12 officers and injuring 15 others.

Axar.az reports, citing The Kyiv Independent, that this was told by Unmanned Systems Forces commander Robert "Madyar" Brovdi on Telegram.

A series of explosions rocked Donetsk at around 8 a.m. local time on April 22, and videos began circulating on social media showing what appeared to be Ukrainian drones striking a multi-story unfinished building.

Ukrainian forces used FP-2 drones manufactured by the Ukrainian defense company Fire Point and designed for medium-range strikes, with a payload of 60 to 100 kilograms, Brovdi said.
