Ukraine war: Odesa port reopens after energy network hitOperations have resumed at the Ukrainian Black Sea port of Odesa after Russia used Iranian-made drones to hit energy facilities in the city.Thousands of people have made use of the region's "points of invincibility" - facilities which supply electricity and warmth to residents during blackouts.The strikes on Ukraine's energy infrastructure, which intensified in mid-October, have left millions of people in nearly all regions of the country without power, as temperatures drop below zero.A complete blackout across the entire country is a now realistic scenario, Ukraine's Foreign Minister Dmytro Kuleba told German television on Sunday.Russia's frequent attacks on Ukraine's power grid have led to calls for the West to supply Kyiv with better air defence weapons."
