US says Russia's claim of withdrawing troops from border with Ukraine is false

The United States does not believe Russia's claim to be withdrawing troops from the Ukraine border and suspects Moscow has increased its presence by as many as 7,000 troops, a senior Biden administration official said on Wednesday.

"So yesterday, the Russian government said it was withdrawing troops from the border with Ukraine....But we now know it was false," the official told reporters without offering details or providing evidence.

The official, who spoke on condition of anonymity, said the Biden administration confirmed that "Russia has increased its troop presence along the Ukrainian border by as many as 7,000 troops" with many of them arriving as recently as Wednesday.

The senior administration official also said Russia has publicly claimed to engage in diplomacy and made claims of "de-escalation" while "privately mobilizing for war."

Russia's defence ministry said Wednesday its forces were pulling back after exercises near Ukraine and published video that it said showed forces leaving the Crimean peninsula.

But US Secretary of State Antony Blinken said in an interview on MSNBC on Wednesday that "critical units" were moving towards the border.

The senior administration official said the United States continued to receive information that suggests Russia can "launch a false pretext at any moment" to justify an invasion of Ukraine. The official pointed to an increase in false claims and disinformation online by Russia in recent days.
