KYIV — More than a million households across Ukraine were left without electricity after overnight Russian strikes hit energy and industrial infrastructure, Ukrainian officials said.

Interior Minister Ihor Klymenko said five regions were affected and at least five people were injured.

He said emergency crews were working to extinguish fires and restore power supplies.

The attacks struck the Dnipropetrovsk, Kirovohrad, Mykolaiv, Odesa and Chernihiv regions, according to Ukrainian authorities. President Volodymyr Zelensky said Russia used more than 450 drones and 30 missiles in the overnight barrage.

Russia’s Defense Ministry said the strikes included the use of Kinzhal hypersonic missiles, which can change direction mid-flight and are difficult to intercept.

The International Atomic Energy Agency said Ukraine’s Zaporizhzhia nuclear power plant temporarily lost all offsite power due to widespread military activity affecting the electrical grid, but was later reconnected.

The Russian-controlled plant is not operating but requires continuous power to cool its reactors.

In Russia, regional governor Roman Busargin said two people were killed in the Saratov region after a drone strike hit a residential building.

The latest strikes come as US President Donald Trump’s envoy, Steve Witkoff, is expected to travel to Germany this weekend to meet Zelensky and European leaders for further talks aimed at ending the war.

Witkoff has been leading White House efforts to mediate between Ukraine and Russia.

The Trump administration is pushing for a deal to be reached by Christmas, though recent negotiations have shown little sign of a breakthrough.

Zelensky has expressed skepticism about elements of a proposed peace plan, particularly provisions related to territorial arrangements in eastern Ukraine.

Meanwhile, European governments are weighing how to support Ukraine financially and militarily should a peace agreement be reached. Ukraine faces an estimated funding gap of €135.7 billion over the next two years.

On Friday, EU nations agreed to indefinitely freeze about €210 billion worth of Russian assets held in Europe, a move intended to pave the way for potential financial support to Ukraine. Russia has condemned the decision and said it plans legal action. — Agencies
