The US will provide nearly $1 billion more in longer-term weapons support to Ukraine, Defence Secretary Lloyd Austin said on Saturday as the Biden administration rushes to spend all the congressionally approved money it has left to bolster Kyiv before President-elect Donald Trump takes office next month.

The latest package will include more drones and munitions for the High Mobility Artillery Rocket Systems, or HIMARS, that the US has provided. While these weapons are critically needed now, they will be funded through the Ukraine Security Assistance Initiative, which pays for longer-term systems to be put on contract.
