Ukrainian forces launched a large drone strike on Russian positions in occupied Donetsk on Thursday evening, according to local Telegram channels.
Donetsk in eastern Ukraine has been under Russian occupation since 2014. The city hosts major industrial sites and remains one of the main rear areas supporting Russian forces in the east.
Residents reported the sound of dozens of drones around 8pm, followed by intense Russian anti-aircraft fire across several districts.
Videos show gun and machine-gun fire directed at low-flying targets, which Ukrainian defense portal Militarnyi says suggests earlier strikes may have disabled some Russian missile and radar systems.
Footage from the scene captures the sound of drone engines, bursts of anti-aircraft fire, and at least one blast. A major fire was later visible at the Donetsk Metallurgical Plant, with several thick columns of smoke rising from the area.
Parts of the city lost power during the attack, pointing to possible damage to energy infrastructure. Witnesses said the drones arrived in waves and circled over the city for an extended period.
Militarnyi reports, based on the released clips, that the strike appears to have involved FP-2 kamikaze drones produced in Ukraine.
