A decision by Washington to halt some shipments of critical weapons to Ukraine triggered warnings in Kyiv on Wednesday that the move would weaken its ability to defend against intensifying Russian air strikes and battlefield advances.

Ukraine is moving forward with plans for joint weapons production with allies while the U.S. halts some arms shipments.

The move "was made to put America’s interests first," a White House spokeswoman said, as U.S. munitions have been depleted in recent years.
