That comes a day after the Trump administration lifted its suspension of military aid for Kyiv in its war against Russia and Ukrainian officials signaled they were open to a 30-day ceasefire backed by Washington.

The U.S. official said the U.S. provided fewer than 40 of those missiles overall and that Ukraine ran out of them in late January. Senior U.S. defense leaders, including the previous Pentagon chief, Lloyd Austin, had made it clear that only a limited number of the ATACMs would be delivered and that the U.S. and NATO allies considered other weapons to be more valuable in the fight.
