Biden believes Putin has decided to invade Ukraine

US President Joe Biden has said he is convinced Russian President Vladimir Putin has decided to launch an invasion of Ukraine, and that an assault could happen in the "coming days," reported British Broadcasting Corporation (BBC).

Biden made the assessment based on the report from US intelligence, which suggested the Ukraine capital Kyiv would be targeted.

Russia, however, denied the claim of any planning to invade.

Western nations accuse Russia of trying to stage a fake crisis in breakaway eastern regions of Ukraine to give it a reason to launch an offensive, said the BBC report.

The US estimates there are 169,000-190,000 Russian personnel massed in and near Ukraine, a figure that includes Russian-backed fighters in the self-proclaimed republics of Donetsk and Luhansk in eastern Ukraine, the report added.
