The Trump administration will hold back delivering to Ukraine some air defense missiles, precision-guided artillery and other weapons as part of its announced pause to some arms shipments amid U.S. concerns that its own stockpiles have declined too much,

The details on the weapons in some of the paused deliveries were confirmed by a U.S. official and former national security official familiar with the matter.

Ukraine has expressed concern that Russia may be emboldened after the United States put a pause on a shipment of armament to Ukraine due to lessened stockpile concerns.
