The United States is expected to announce a new $400 million package of weapons for Ukraine

WASHINGTON (AP) — The U.S. is expected to announce a new $400 million package of military aid for Ukraine on Friday, U.S. officials said, as Kyiv struggles to hold off advances by Russian troops in the northeast Kharkiv region.

This is the third tranche of aid for Ukraine since Congress passed supplemental funding in late April after months of gridlock. Ukrainian President Volodymyr Zelenskyy had warned Thursday that his country was facing “a really difficult situation” in the east, but said a new supply of U.S. weapons was coming and “we will be able to stop them.”

According to officials, the package includes artillery, air defense and anti-tank munitions, armored vehicles and other weapons and equipment. The officials spoke on condition of anonymity because the aid has not yet been announced. It will be provided through presidential drawdown authority, which pulls systems and munitions from existing U.S. stockpiles so they can be sent quickly to the war front.
