US will announce $275 million more in artillery and ammunition for Ukraine

The United States is expected to announce an additional $275 million in military aid for Ukraine on Friday as Kyiv struggles to hold off advances by Russian troops in the Kharkiv region, two U.S. officials say.
This will be the fourth installment of military aid for Ukraine since Congress passed a long-delayed foreign aid bill late last month and comes as the Biden administration has pledged to keep weapons flowing regularly and to get them to the front lines as quickly as possible.
