Washington, 30 December 2024 (dpa/MIA) - Outgoing US President Joe Biden has announced another tranche of security assistance for Ukraine worth some $2.5 billion, as he seeks to bolster Kiev's defences against the Russian invasion before leaving office in January.

The aid had already been approved by Congress and covers both weapons and ammunition worth $1.25 billion for the Ukrainian military as well as another $1.22 billion in security assistance, according to a statement released by the White House.

Biden said his administration was determined to "fully" utilize all funding for Ukraine allocated by Congress.

"At my direction, the United States will continue to work relentlessly to strengthen Ukraine's position in this war over the remainder of my time in office," he said.

Under Biden, the US has been the most important backer of Ukraine in the war launched by Russia on February 24, 2022, but fears are growing that that could change once US President-elect Donald Trump takes office on January 20.

Biden said the latest package "will provide Ukraine with both an immediate influx of capabilities that it continues to use to great effect on the battlefield and longer-term supplies of air defense, artillery, and other critical weapons systems."

"The Department of Defense is in the process of delivering hundreds of thousands of artillery rounds, thousands of rockets, and hundreds of armored vehicles which will strengthen Ukraine’s hand as it heads into the winter," he added.
