The U.S. Department of Defense announced another $1 billion in long-term aid to Ukraine on Saturday, as a Pentagon fund designed to support the war effort is running dry.

In a press release, the Pentagon said the new aid package includes $988 million from the Ukraine Security Assistance Initiative, a fund that had a little over $2 billion left before the announcement. Also included in the aid package are drones and munitions for the High Mobility Artillery Rocket Systems.
