The United States is expected to announce a new security assistance package for Ukraine totaling about $3 billion as it tries to beat back invading Russian forces.
President Joe Biden's administration could make the announcement as early as August 24 to coincide with Ukraine's Independence Day, a U.S. official told media.
The tranche would be the single largest aid package to Ukraine since Russia launched its unprovoked invasion six months ago.
U.S. military aid, including the transfer of multiple rocket launchers and howitzers, has played a major role in helping Ukraine grind down Russia’s larger and better-equipped forces on the eastern front.
The U.S. official, who spoke on condition of anonymity, did not disclose what weapons would be transferred to Ukraine under the latest tranche.
The United States has provided $10.6 billion in military assistance to President Volodymyr Zelenskiy's government since Feb. 24.
Separately, Germany said on the same day that it will soon ship more than 500 million euros' ($499.3 million) worth of weapons to Ukraine.
Earlier this year Germany wrestled with the question of whether it should supply armaments to Ukraine, resulting in long delays that were the subject of considerable criticism both domestically and abroad.
The U.S. and German announcements come amid fears that Russia could launch missile strikes on Ukrainian cities on August 24 as citizens celebrate 31 years of independence from Moscow.
