Missiles and drones launched by Russia in an intense series of nation-wide nightime air attacks have damaged critical port infrastructure in southern Ukraine, including grain and oil terminals, and wounded at least 12 people, Ukrainian officials said on Wednesday.

The air raid targeted the southern port city of Odesa for a second night in a row, days after Russian President Vladimir Putin said Moscow would halt its participation in the Black Sea Grain Initiative, which enabled crucial grain exports to the world, including many countries facing the threat of hunger.
