The slowing of some weapons shipments promised to Kyiv by former president Joe Biden’s administration came in recent days, they said, adding that air defence interceptors to help knock down Russian drones and projectiles are among the items delayed.

In an email, the Pentagon said it was providing President Donald Trump with options to continue military aid to Ukraine in line with the goal of ending Russia’s war there.

“At the same time, the department is rigorously examining and adapting its approach to achieving this objective while also preserving US forces’ readiness for administration defence priorities,” said Elbridge Colby, the undersecretary for policy.

Russia, which already controls about a fifth of Ukraine, continues to advance gradually, gaining ground in recent weeks in Ukraine’s southeastern regions of Donetsk and Dnipropetrovsk, and ramping up air attacks nationwide.

All weapons aid was briefly paused in February with a second longer pause in March. The Trump administration resumed sending the last of the aid approved under Biden.

No new policy has been announced.

Politico reported the pause on Tuesday.
