With Russian forces withdrawing from some areas of Ukraine, details are emerging of the death and destruction they have left behind. In Borodyanka, 60 km north-west of Kyiv, the main road through the town is lined with destroyed and burnt-out buildings, vehicles and tanks. Olga and Ira lived there and have sent us messages, describing how their homes were bombed. We hear from Vitaliy Shevchenko, the Russian Editor for BBC Monitoring, who as well as covering the war for us, has been trying to get his parents out of Ukraine to safety.
