A drone struck a five-story apartment building in Russia on Saturday morning, and some media outlets in the country pointed the finger at Ukraine.
Residents of the building in St. Petersburg reported a strange sound, an explosion, and then a fire just after 7 a.m. local time.
“At first I heard a whistle, because I had just opened the window, and then the window flew out, and the fire broke out and the apartment was filled with smoke,” Elena, a resident, told Reuters news agency.
The Russian National Guard in Rosjvardia said 100 people had been evacuated, while Russian news agency RIA Novosti said six people needed medical assistance after the explosion.
A video clip from the scene showed the facade of the building with shattered windows, damaged balconies, shattered glass, and debris on the ground.
Russian media said that the accident may have been caused by the downing of a Ukrainian drone that was heading towards a nearby fuel depot.
The Ukrainian Defense Ministry said it had “no information about the referred situation” and the Russian Defense Ministry did not comment.
