During the night, Russian missile and drone strikes have caused blackouts in extensive areas of Ukraine's capital, Kyiv.
A number of civilians were injured while residents in eastern districts were experienced blackouts and dealt with disruption to drinking water, according to local authorities.

"What's needed is not symbolic gestures but firm measures - from the America, European nations and the major economies - in providing air defence systems and implementing restrictions," mentioned in a social media post.
Officials stated that numerous aerial vehicles and over thirty rockets struck Ukraine's energy infrastructure, describing such strikes as "cynical and calculated" and against "critical infrastructure" as winter approaches.
The energy minister said Russia was "launching a major assault" and repair crews were striving to repair systems.
A series of attacks struck energy infrastructure and residential structures in the capital.
Several of the people wounded in the assaults on the city have been taken to hospital, per statements from local officials.
Area administrators said the city experienced significant strikes overnight. A young boy died and three other people were wounded.
The strikes come after evenings of bombing campaigns in the area, sections of which are currently controlled by Russian forces.
The entire country is on alert for advanced weapon attacks, which are more difficult to detect.
Authorities told journalists that Moscow was deliberately attempting to demolish the country's energy grid, with attacks already impacting fuel infrastructure.
He said utility staff and authorities were preparing for more assaults.
