In southwestern Russia, a Ukrainian drone strike set off fires at the Black Sea port of Taman on Sunday in an attack that wounded two people and damaged an oil storage tank, warehouse and terminals. Elsewhere, debris from Russian drones damaged infrastructure in Ukraine’s Odesa region, disrupting water and electricity supplies to civilians. The violence comes ahead of a new round of U.S.-brokered talks involving Russian and Ukrainian envoys who will meet in Geneva on Tuesday and Wednesday.

Meanwhile, a report by U.K. and European nations issued Saturday finds Russian opposition leader Alexei Navalny’s death in a Siberian penal colony in 2024 was likely due to a deadly toxin found in the skin of Ecuadorian poison dart frogs. The toxin was reportedly found in “smuggled” samples taken from Navalny’s body.
