Ukrainian drones hit Russia's Sochi resort while Russian forces bombarded Odessa's residential areas and historic Pryvoz market, hours after ceasefire talks collapsed.

Russia and Ukraine again exchanged a series of major overnight drone strikes as the two sides maneuvered ahead of a possible resumption of ceasefire talks.

Russia and Ukraine launched drone strikes against each other early on July 24, officials from both sides said, as fierce fighting continued to rage along the battlefield.
