Russia has unleashed a barrage of missiles on the Ukrainian city of Mykolaiv, after the United Nations General Assembly condemned Moscow's attempted annexation of four Ukrainian areas and Kyiv's allies committed more military aid.A shipbuilding centre and a port on the Southern Bug river off the Black Sea, Mykolaiv has suffered heavy Russian bombardments throughout the war.AdvertisementIn New York, three-quarters of the 193-member General Assembly - 143 countries - voted on Wednesday in favour of a resolution that called Moscow's move illegal, deepening Russia's international isolation.In Brussels, more than 50 Western countries met to pledge more military aid to Ukraine, especially air defence weapons, on the heels of heavy retaliatory strikes this week ordered by Russian President Vladimir Putin in response to an explosion on a bridge in Crimea.As his forces have lost ground on the battlefield since September, Mr Putin has escalated the conflict, ordering the call-up of hundreds of thousands of reservists, proclaiming the annexation of occupied Ukrainian territory and repeatedly threatening to use nuclear weapons to protect Russia."
