Key developments on July 2: As Russia ramps up missile attacks, US halts promised air defense shipments to Ukraine North Korea to send up to 30,000 more troops to aid Russia's war against Ukraine, CNN reports Ukraine denies another Russian claim of Dnipropetrovsk Oblast breakthrough, says small incursion repelled Russia's Kupol military plant reportedly halts operations after Ukrainian drone strike Russia killed at least 273 Ukrainian POWs during full-scale war, prosecutors say The U.S. Defense Department (DOD) has halted shipments of some air defense missiles and other weapons previously promised to Kyiv out of concerns over the size of U.S. stockpiles, Politico reported on July 1, citing sources familiar with the matter. The suspension comes as Ukraine faces a shortage of air defense munitions along with increasingly intense and deadly Russian bombardments. In June 2025, Russia launched 5,337 Shahed-type drones at Ukraine, shattering its previous monthly record. Pentagon policy chief Elbridge Colby made the decision to pause the aid deliveries after conducting a review of U.S. munitions stocks, three sources told Politico. Colby was reportedly concerned about dwindling levels of artillery rounds, air defense missiles, and precision munitions.
