Two unmanned aerial vehicles (UAVs) damaged buildings in Krasnodar on Friday, after local media reported that an explosion was heard in the southern Russian city.
The governor of Krasnodar Veniamin Kondratiev said no major infrastructure was impacted, and said there were no casualties following the incident.
On Friday morning, videos geo-located by CNN showed what appeared to be a UAV in the sky followed by the sound of an explosion. Other social media images show smoke rising from the building, and another image shows the building damaged.
State news agency TASS reported that the city's emergency call center was alerted to an explosion on Morskaya Street early Friday.
"Emergency services were sent to the scene. No casualties have been reported. There was damage to the building's roof and windows, but no fire," according to TASS.
