Russia's overnight drone attack on the Black Sea port city of Odesa damaged residential buildings, warehouses and civilian infrastructure, Ukrainian officials from the region said early on Wednesday.

Russian Foreign Minister Sergei Lavrov said that it was not easy to agree with the United States on the key parts of a possible peace deal to end the war in Ukraine and that Russia would never again allow itself to depend economically on the West.

A Russian missile killed 34 people on Sunday in an attack that Trump described as "a mistake" and Germany called "a war crime".
