KYIV, Ukraine — Thirty people were killed and at least 18 were injured by Russian strikes in eastern Ukraine that included an attack on a public bus, authorities said Thursday, as an intensive pre-winter wave of attacks continued and power outages worsened in the capital Kyiv. Vadym Filashkin, head of the regional military administration, said public transport in Kramatorsk and the neighboring city of Sloviansk, in Ukraine’s Donetsk region, was halted because of the sharp deterioration in security. He accused Russia of deliberately targeting civilians, adding, “In such circumstances, we have no right to risk the lives of passengers and drivers. The safety of residents of Kramatorsk and Sloviansk is above all.” The attacks follow deadly missile strikes a day earlier in the northern Ukrainian town of Pryluky, where the death toll rose to 22, including five children. Rescuers searched through the rubble of a residential building hit by a Russian missile and at least 54 people were injured. Heavy debris was removed from the cratered section of the building, while rescue dogs continue
