With Ukraine suffering military setbacks since the failure of a counteroffensive last summer, Macron had last month shocked some allies by not ruling out sending Western troops to Ukraine.

Biden said the stopgap shipment of missiles, shells and ammunition for Kyiv was "not nearly enough" and would run out in a couple of weeks.
