Russia and Ukraine have made competing claims about who is gaining ground, as Russian strikes keep hitting Ukrainian cities and U.S.-backed talks in Turkey were postponed. A Ukrainian general said Kyiv's forces push Russians back in parts of the Dnipropetrovsk region. Another Ukrainian officer tells the AP that troops have advanced more than 6 miles, while Russia's leader said his army expanded gains in the Donbas. There was no independent verification of either side's claims. Meanwhile, Russian glide bombs hit Sloviansk and killed four people and drone attacks wounded more civilians, a Ukrainian official said Tuesday.
