Russia and Ukraine are accusing each other of deadly drone strikes on civilian areas as Ukrainian President Volodymyr Zelenskyy anticipates a busy week at the U.N. General Assembly in New York.

Russia unleashed intense overnight drone and missile attacks that officials said damaged critical port infrastructure in southern Ukraine, including grain and oil terminals, and wounded at least 12 people.

Russian-installed authorities in the Crimean peninsula have reported shooting down a cruise missile near the city of Kerch and briefly suspending traffic on the Kerch bridge that links the annexed territory to Russia.

The Moscow-appointed leader of Crimea says the region is on guard for what may be an impending Ukrainian counteroffensive.
