US President Joe Biden is all set to deliver an update on the Russian invasion of Ukraine on Thursday as he works to complete a new arms package for its military.

The US President is set to address Americans from the White House Roosevelt Room at 9:45 am (1345 GMT), Reuters reported and said that he is “expected to provide an update on the efforts to support Ukraine and the assistance we are providing.”

Earlier, speaking to Reuters, another US official said that the new arms package was likely to be roughly the same size as an $800 million one announced last week but details were still being worked out.

On Wednesday, Biden convened US military leaders in an annual White House gathering that took on special significance as the war enters a risky new phase.

Opening the meeting, Biden touted the toughness of the Ukrainian military and said that NATO’s unity had shocked Russian President Vladimir Putin.

It is reported that Russia has entered a new stage of its operation and is methodically seeking to “liberate” the Donbas region of eastern Ukraine.
