U.S. President Joe Biden promised new military aid for Ukraine worth $500 million during a surprise visit to Kyiv on Monday, almost a year to the day since Russia's invasion.
Biden also said additional sanctions would be announced this week against the Russian elite and companies trying to evade sanctions to "back the Russian war machine."
The military aid package will include artillery ammunition, anti-armor systems and air surveillance radars "to help protect the Ukrainian people from aerial bombardments," he said.
