European Union diplomats scrambled Monday to overcome Hungary's veto threats as they seek to finalize new sanctions on Russia and a massive new loan for Ukraine.

EU foreign policy chief Kaja Kallas said the bloc's 27 foreign ministers gathering in Brussels would likely not agree on the 20th package of sanctions targeting Russia's shadow fleet and energy revenues, which it hoped to pass ahead of the fourth anniversary Tuesday of Russia's all-out invasion of Ukraine — a war that has left perhaps 1.8 million dead, wounded or missing.
