The United States on Monday announced a new package of $400 million in arms for Ukraine during Defense Secretary Lloyd Austin's visit to Kyiv.

"I'm pleased to announce today a commitment of a $400 million presidential drawdown package to provide your forces with additional munitions, armored vehicles and anti-tank weapons," Austin said, speaking at a meeting with Ukrainian President Volodymyr Zelenskyy.

Austin arrived in Kyiv earlier on Monday in an unannounced visit. It marks his fourth visit to Ukraine as the secretary of defense.
