Russia and Ukraine started a major prisoner exchange on Monday after days of wrangling cast doubt over the only concrete result of peace talks last week in Turkey.

Warner Bros Discovery said on Monday it would split into two companies, separating its studios and streaming business from its fading cable television networks as the parent of HBO and CNN looks to compete better in the streaming era.

Russia said on Monday that its forces had taken control of more territory in Ukraine's east-central region of Dnipropetrovsk, where the Kremlin said fighting was partly aimed at creating a "buffer zone.

Russia said its ground forces crossed into Ukraine’s central Dnipropetrovsk region for the first time, a symbolic milestone in their grinding offensive as prospects for a US-brokered ceasefire remain elusive.

Russia claimed Sunday that its forces are for the first time pushing into the central Ukrainian region of Dnipropetrovsk, an area it has been trying to reach for months, in a move that could create new problems for Kyiv’s much-stretched forces.
