Ukraine and Russia launched fresh airstrikes along the Black Sea early Thursday, shortly after peace talks in Istanbul failed to yield progress.

Russian drones hit Odesa, injuring four and damaging the city’s historic center, including the Pryvoz market. In Russia’s Sochi region, falling drone debris killed one woman and injured another, and briefly shut down the airport after a strike on an oil facility, according to Reuters.

Ukraine’s Cherkasy region was also hit, with seven injured, including a child. Ukrainian President Zelensky said Russia responded to ceasefire proposals with more drone and missile attacks, targeting civilian and transport sites.
