KYIV/DNIPRO, Ukraine (Reuters) -Ukraine shot down a Russian strategic bomber 300 km (185 miles) from its border on Friday after the warplane took part in an airstrike that killed at least eight people, including two children, in the central Dnipropetrovsk region, Kyiv said. Missiles rained down on the city of Dnipro and the surrounding region in the early hours, damaging residential buildings, the main train station and wounding at least 28 civilians, regional officials said. Russia has stepped up its long-range aerial assaults on Ukraine's energy system and other targets in recent weeks, ratcheting up the pressure on Kyiv far behind the front lines where Russian forces have been slowly advancing in the east.
