A powerful blast rocked the Russian city of St. Petersburg early on Saturday when a drone crashed into an apartment block, local media have reported.
The explosion occurred in the northern part of the city, and the facade of a residential block was “seriously damaged.”
St. Petersburg Mayor Alexandr Beglov declined to say whether it was a drone strike.
Local residents report that before the explosion they heard the sound of an engine and saw a bright flash in the sky.
Debris fell next to one of the houses, probably from an unmanned aerial vehicle.
The likely target of the Ukrainian UAV was the Ruchi oil depot in the northeast of St. Petersburg - less than a kilometer from the crash site.
Preliminarily, there were no casualties.
“There have been no casualties. The balcony windows of two buildings were partially damaged. Residents of the affected apartments have been evacuated,” he wrote on Telegram, adding that police and emergency services were working at the scene.
The press service of the St. Petersburg Health Committee later reported that six people sought medical help following the incident.
