Shipments of American weapons could begin flowing to Ukraine again soon after a long-stalled aid package becomes law, U.S. officials say, with goods from the Pentagon¡¯s stockpiles in Germany to be shipped quickly by rail to the Ukrainian border.

The measure would provide the Ukraine war effort with about $60 billion. A sizable amount is set aside to replenish U.S. defense stockpiles, and billions more would be used to purchase U.S. defense systems, which Ukrainian officials say are badly needed.

In a statement Saturday after the House approved the aid package, President Joe Biden urged the Senate to swiftly take up the measure to help meet Ukrainian forces¡¯ ¡°urgent battlefield needs.¡± It was expected to do so as early as Tuesday.
