Russia pummeled Ukraine’s second-largest city, Kharkiv, overnight on Saturday, using a swarm of drones, bombs and missiles that killed at least three people. The local authorities said that within 90 minutes, Russia struck the city with nearly 50 drones, two missiles and four glide bombs, powerful guided weapons that carry hundreds of pounds of explosives. The attack came as Russian forces about 100 miles north of Kharkiv pushed deeper into Ukraine’s northeastern Sumy region, seizing two more villages and advancing their effort to carve out a buffer zone along the Russia-Ukraine border.It came just a day after Russia launched one of its biggest air assault of the war across Ukraine, involving more than 400 drones and over 40 missiles, in what Russia described as retaliation for Ukraine’s audacious attacks on its strategic bomber bases last weekend. Is Russia winning or losing the war ?
