Kyiv's mobile air defenses have enough ammunition to withstand a few more powerful attacks but then will need more Western aid, Serhiy Nayev, the commander of Ukraine's joint forces, said on January 3. Late last year, Russia launched its largest missile and drone attacks since the early days of the invasion. It then bombarded the capital and Ukraine's second-largest city, Kharkiv, on January 2, killing five and injuring dozens. "The current situation with man-portable air defense systems for mobile air-defense groups is that there is enough ammunition to withstand the next few powerful attacks," Nayev told the AFP news agency.
