Ukraine has received more American-made Patriot air defense systems to help it counter Russia’s daily barrages, President Volodymyr Zelenskyy said, as Russian drones killed a man and injured five of his family members, including two children, in the latest nighttime attack. Russia’s relentless pounding of urban areas behind the front line following its full-scale invasion of Ukraine nearly four years ago has killed thousands of civilians. It has also targeted the energy supply to deny civilians heat and running water in winter, as well as disrupt industrial production of Ukraine’s newly developed drones and missiles.
