- NATO's chief said Ukraine is expending an "enormous" amount of munitions on the battlefield.
- Kyiv is firing these munitions faster than the US and its European partners can produce them, he said.
- NATO members and partner countries have sent tens of billions of dollars in military aid to Ukraine.
