Kyiv Mayor Vitalii Klitschko said explosions were heard in the Ukrainian capital and warned people to stay in shelters late on Tuesday night as air defences worked to repel a Russian attack.
Russian forces launched a “massive” drone attack on Ukraine’s Sumy region, targeting energy infrastructure and causing electricity blackouts, Governor Oleh Hryhorov said on Telegram late on Tuesday night.
Power outages were also reported in the Donetsk region, Ukrainian Deputy Minister of Energy Mykola Kolisnyk said.
A Russian attack on electrical substations and other energy infrastructure left 280,000 households in Ukraine’s Odesa region without power, Governor Oleh Kiper wrote on Telegram.
Electricity was later restored to 220,000 homes, Kiper said, but extensive work was still needed to repair damaged networks.
The Russian-occupied Zaporizhzhia nuclear power plant in Ukraine is currently receiving electricity through only one of two external power lines, the facility’s Russian management said, after the other line was disconnected due to military activity.
Russian forces shot down 180 Ukrainian drones in one day, Russia’s Ministry of Defence said, according to the state-run TASS news agency.
The ambassador-at-large of the Russian Ministry of Foreign Affairs, Rodion Miroshnik, told TASS that Ukrainian attacks had killed 14 Russian civilians and injured nearly 70, including in the Russian-occupied Kherson and Zaporizhia regions of Ukraine, over the past week.

German Chancellor Friedrich Merz shared details about a potential European-led multinational force being considered as part of discussions on security guarantees for Ukraine.
“We would secure a demilitarised zone between the warring parties and, to be very specific, we would also act against corresponding Russian incursions and attacks,” Merz told ZDF public television, adding that the talks “we’re not there yet”.

Bulgaria, Estonia, Finland, Latvia, Lithuania, Poland, Romania and Sweden said in a joint statement on Tuesday that “Russia is the most significant, direct and long-term threat to our security and to peace and stability in the Euro-Atlantic area”.
After the Eastern Flank Summit in Helsinki, Finland, Polish Prime Minister Donald Tusk said that the grouping of European countries discussed an “anti-drone wall” that would require “billions in expenditure here”.
Germany’s Federal Ministry of Defence said that it ended the deployment to Poland of its Patriot systems and soldiers from its Air and Missile Defence Task Force, after the mission concluded as planned.
UK Secretary of State for Defence John Healey said the United Kingdom is spending 600 million pounds (more than $800 million) to buy “thousands of air defence systems, missiles, and automated turrets to shoot down drones” for Ukraine, during a virtual meeting of the Ukraine Defence Contact Group, according to the Kyiv Independent news outlet.
German Defence Minister Boris Pistorius told the same meeting that Germany would “transfer a significant number of AIM-9 Sidewinder missiles” to Ukraine next year.

The leaders of 34 European countries signed an agreement in The Hague to create an International Claims Commission for Ukraine to seek compensation for hundreds of billions of dollars in damage from Russian attacks.
“Every Russian war crime must have consequences for those who committed them,” Ukrainian President Volodymyr Zelenskyy said before signing the agreement.
“The goal is to have validated claims that will ultimately be paid by Russia. It will really have to be paid by Russia,” Dutch Minister of Foreign Affairs David van Weel said.
