The Russian defence minister has said his troops will increase the intensity of strikes on logistics centres and the storage depots of Western weapons in Ukraine.
Sergei Shoigu addressed the new US military aid package for Ukraine, worth nearly $61bn, in remarks to defence officials.
In an apparent reaction to the aid package, Mr Shoigu said: "In proportion to the threats posed by the United States and its allies, we will continue to improve the composition and structure of the armed forces and increase the production of the most popular weapons and military equipment.
"We will increase the intensity of attacks on logistics centres and storage bases for Western weapons."
As part of the package, President Volodymyr Zelenskyy said Kyiv will soon receive more long-range ATACMS missile systems.
US officials said the aid will also include ammunition supplies and interceptors for air defence systems.
The in-demand aid package will be voted on in the US Senate later today, where it is likely to pass. President Joe Biden has promised to sign it into law immediately after this.
