Russian drone strikes killed one person and injured three on Friday evening, according to Ukraine’s National Police.
The strikes caused a fire at a residential building in Odesa, the police said on Saturday, adding that the blaze had since been extinguished.
One of the injured was rescued from the rubble of the building; all three were hospitalized.
Oleh Kiper, head of the Odesa region military administration, said that a 72-year-old woman suffered severe burns and fractured limbs after remaining under the rubble for almost two hours.
The other two injured were a mother and a daughter, he said.
The mother, over the age of 60, suffered severe burns over 70% of her body, while her daughter, who is in her thirties, also suffered severe burns along with numerous fractures.
