Russian drone attacks across Ukraine injured at least 11 people, including two children, and damaged residential buildings and civilian infrastructure, Ukrainian officials said on Friday.

A Russian drone struck a residential home in Zhytomyr Oblast on Thursday, injuring nine people, including two children, according to regional Governor Vitalii Bunechko.

"Russia continues its deliberate terror against the peaceful Zhytomyr Oblast," Bunechko wrote on Telegram.

Two of the injured were taken to hospital, while the full extent of the injuries was not immediately clear.

Zhytomyr, a city in northwestern Ukraine with a population of more than 200,000, has faced repeated Russian attacks on its energy infrastructure in recent weeks.

Russian strikes on Ukrainian energy facilities have intensified ahead of the winter months, raising concerns about the impact on heating, electricity and water supplies. Earlier attacks left hundreds of thousands of people in Kyiv and frontline cities facing repeated power and water outages.

Elsewhere, explosions were reported overnight into Friday in Lutsk, a city in northwestern Ukraine, according to local media.

In Poltava Oblast, a drone crash caused an explosion that damaged private homes, other buildings and a power line, regional military administration head Vitalii Diakivnych said on Telegram. No casualties were reported in the initial assessments.

In northeastern Sumy Oblast, a "massive attack" involving Russian drones targeted civilian infrastructure overnight, injuring two people, regional Governor Oleh Hryhorov said.

The latest attacks came as Ukraine continued to face Russian aerial strikes targeting residential areas and critical infrastructure, with Ukrainian authorities warning of mounting risks as temperatures fall and winter approaches. (ILKHA)
