Putin call comes after the U.S. said it would halt some weapons shipments to Ukraine, which continues to fight off invading Russian forces.

Ukrainian authorities are enlisting European help to increase domestic military production as the United States pauses some weapons shipments to Ukraine.

The Kremlin has repeatedly said arms shipments to Ukraine from allies prolong the conflict Moscow started and raise the risk of escalation. The U.S. confirmed this week it had paused supplying some arms to fight Russian aggression.

An emboldened Russia has ramped up military offensives on two fronts in Ukraine, scattering Kyiv’s precious reserve troops and threatening to expand the fighting to a new Ukrainian region as each side seeks an advantage before the fighting season wanes in the autumn.
