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 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 that Moscow would halt its participation in the Black Sea Grain Initiative, which enabled crucial grain exports to reach the world, including many countries facing the threat of hunger.

Meanwhile, Russian emergency officials in Crimea said that more than 2,200 people were evacuated from four villages because of a fire at a military facility. The fire also caused the closure of an important highway, according to Sergey Aksyonov, the Russia-appointed head of the peninsula, which was annexed in 2014.

He didn't specify a cause for the fire at the facility in Kirovsky district, which came two days after an attack on a bridge linking Russia to Crimea that the Kremlin has blamed on Ukraine.
