“We are looking very closely at the level of Ukraine’s use of (supplied) weapons to make sure they have everything they need,” RIA Novosti quoted her as saying.
She noted that the United States is investing in the production of weapons along with allies "to continue to support Ukraine."
On October 4, US President Joe Biden announced the provision of a new tranche of $625 million to Ukraine.
The new military assistance package includes four HIMARS MLRS, 32 howitzers and 200 armored vehicles, as well as tens of thousands of shells and mines.
