Kyiv, Aug 3: Russian planes dropped eight powerful glide bombs in 90 minutes on residential districts of the southern Ukrainian city of Zaporizhzhia, killing one person and wounding dozens of others, regional chief Ivan Fedorov said Monday. Russia has used glide bombs to smash Ukrainian towns and cities since it invaded its neighbour more than four years ago. The weapons are Soviet-era bombs retrofitted with guidance systems and can carry up to 3,000 kilograms (6,600 pounds) of explosives, leaving huge craters. The Sunday evening onslaught on Zaporizhzhia killed a 71-year-old woman and wounded 31 people, including a 16-year-old girl, as the bombs damaged 22 apartment buildings in four districts of the city, Fedorov said.
