A Russian drone attack on Ternopil during the night of Dec. 2 caused a fire in a residential building and resulted in casualties, local officials reported.
Ternopil Mayor Serhiy Nadal said that a drone struck the top floor of a high-rise building, with flames engulfing several floors and partially damaging others.
The attack killed at least one person and injured three, the State Emergency Service said.
Emergency and rescue teams worked through the night to extinguish the fire and assist the injured while temporary shelters were prepared for displaced residents.
"Doctors are doing everything possible to save the wounded," Nadal said.
Ternopil is a city in western Ukraine with a population of roughly 225,000. Lying hundreds of kilometers from the front line, the city is not a common target of Russian attacks.
