U.S. President Joe Biden on Monday announced nearly $2.5 billion in additional security assistance for Ukraine.

The announcement includes an additional $1.25 billion drawdown package for the Ukrainian military and a $1.22 billion Ukraine Security Assistance Initiative (USAI) package, Biden said in a statement.

"As I committed earlier this year, the Department of Defense has now allocated all remaining USAI funds appropriated by Congress in the supplemental that I signed in April, and my administration is fully utilizing the funding appropriated by Congress to support the drawdown of U.S. equipment for Ukraine," Biden added.

He also noted that the U.S. Department of Defense "is in the process of delivering hundreds of thousands of artillery rounds, thousands of rockets, and hundreds of armored vehicles" to Ukraine.
