A critical infrastructure facility in western Ukraine's Khmelnytskiy region was damaged during an overnight Russian drone attack, an official said on Wednesday.
"In Shepetivka district, as a result of the downing of enemy aerial targets, they crashed on the territory of a critical infrastructure facility," a senior official in the Khmelnytskiy region, Sehiy Tiurin, said on the Telegram messaging app.
He said the blast wave damaged non-residential facilities, residential buildings and vehicles and at least 16 people had sought medical treatment for various injuries, Reuters reported.
The Ukrainian military said on Facebook that air forces destroyed all 11 Russian drones launched at Ukraine overnight.
The Khmelnytskiy region has regularly been a target of attacks by Russian drones and missiles, which analysts link to a military airfield in the region.
