Russia, shaken by Ukrainian strike, could step up drone use KYIV, Ukraine (AP) — Emergency crews on Tuesday sifted through the rubble of a building struck by Ukrainian rockets, killing at least 63 Russian soldiers barracked there in the latest blow to the Kremlin’s war strategy as Ukraine says Moscow’s tactics could be shifting.An Associated Press video of the scene in Makiivka, a town in the partially Russian-occupied eastern Donetsk region, showed five cranes and emergency workers removing big chunks of concrete under a clear blue sky.With the fighting raging much longer than anticipated by the Kremlin, and becoming bogged down in a war of attrition amid a Ukrainian counteroffensive backed by Western-supplied weapon s, Russian President Vladimir Putin is mulling ways of regaining momentum.“We have information that Russia is planning a prolonged attack by Shaheds (exploding drones),” Ukrainian President Volodymyr Zelenskyy said in his nightly video address late Monday.As well as seeking to wear down resistance to Russia’s invasion, the long-range bombardments have targeted the power grid to leave civilians at the mercy of biting winter weather as power outages ripple across the country."
