Russian defence ministry says its forces captured Kostiantynivka in eastern Ukraine

Russia says its forces have captured Kostiantynivka in Donetsk; Putin visited a command post and called the city's capture strategically important.
Moscow says it must expand security zones after intensified Ukrainian long‑range/drone strikes — mainly on Russian oil facilities — that have caused fuel shortages.
Ukraine has not confirmed the claim; peace talks are on hold but negotiators are expected to visit soon.
