There was no word from local authorities on whether anyone had been killed. “Ukrainian troops are using weapons transferred from the United States to attack civilians in Donetsk,” Russia’s RIA news agency quoted the leader of Russian-backed separatists in the breakaway Donetsk region, Denis Pushilin, as saying on Russian state television. Reuters could not independently verify which side was responsible for the shelling.Putin said earlier that Russia would strike new targets if the West supplied longer-range missiles to Ukraine. His foreign minister, Sergei Lavrov, said on Monday it would also respond by pushing back Ukrainian forces further from Russia’s border.
