Ukrainian President Volodymyr Zelensky said in a Telegram post that the number of potential victims was ‘unimaginable.’

The aid includes anti-ship missile launchers, howitzers, and more rounds for the High Mobility Artillery Rocket Systems that U.S. forces are training Ukrainian troops on now.

A court in the self-proclaimed Donetsk People’s Republic found the men guilty of working toward a violent overthrow of power, an offense punishable by death in the unrecognized eastern republic.

Western arms have been critical to Ukraine’s success in stymieing Russia’s much larger and better-equipped military.

Ukraine is one of the world’s largest exporters of wheat, corn and sunflower oil, but the war has prevented their export, endangering the world food supply.
