More than 600,000 people in the Kyiv region of Ukraine were without power on Saturday morning after an overnight Russian attack. Ukraine's energy ministry said more than 500,000 of these were in the capital itself, with the rest in the surrounding region. It attributed the power losses to missile and drone strikes on energy infrastructure in the city and several other regions. Around 36 missiles and nearly 600 drones were launched on targets across Ukraine overnight, officials said, killing three and injuring dozens of others. Russia has intensified attacks on Ukrainian civilian and energy infrastructure as the embattled nation heads into winter, despite US-led efforts to secure a peace deal. Russia's defence ministry said it had launched "a massive strike... against Ukrainian military-industrial complex enterprises and the energy facilities that support their operation". Dtek Energy, which serves properties in Kyiv, said later on Saturday that power had been restored to more than 360,000 families. As well as energy infrastructure, several residential buildings were hit in the overnight strikes, Ukrainian officials said. Loud explosions were heard across Kyiv early on Saturday morning. Emergency services were later seen attending to burning blocks of flats damaged by strikes. Kyiv's Mayor Vitaly Klitschko said a 13-year-old child was among the 29 people injured in the capital city.
