Families in Ukrainian cities are taking refuge from massive swarms of Russian drones, as Moscow steps up its airborne assault with attacks designed to undermine Ukrainian morale.

Russia is advancing around Kostyantynivka and in the Sumy region with small, fast-moving units as both sides try a new tactic of using motorcycles and civilian cars to quickly cross open terrain.

Russian forces have changed their tactics for striking Ukraine. Russia is now attacking Ukrainian cities with swarms of lethal drones, informs CNN. CNN noted that Russia has intensified its air attacks on Ukraine in recent weeks.
