Zelenskyy: 'This week, the Russians launched over 3,170 strike drones, more than 1,300 guided bombs, and 74 missiles of various types at Ukraine, most of which were ballistic. There were many hits on residential buildings and other civilian infrastructure. Unfortunately, 52 people were killed in the attacks this week. My condolences to their families and loved ones. Another 346 people were injured, including 22 children.'
