President of Ukraine Volodymyr Zelenskyy has thanked U.S. President Joseph Biden, the Congress and the American people for the newly announced package of military assistance worth $250 million.

"I am grateful to U.S. President Joe Biden, both parties in Congress, and the American people for the security assistance package announced today. Its items are critical to Ukraine's defense, particularly air defense, artillery, and armored capabilities," he said on the X social network on Friday.

The head of state stressed that "American assistance has already saved thousands of Ukrainian lives and this is the kind of leadership that is required."

"This package comes right on the day when we met in the Ukraine Defense Contact Group, Ramstein, for an important discussion with partners and strong steps to support our men and women at the frontline," he said.

Zelenskyy also noted that Ukraine values these decisions and relies on the pledged packages to be delivered and work on the battlefield as soon as possible.

"We continue to stand strong together, defending freedom and countering Russian aggression and terror," he said.
