The UK and US have accused Russia of boosting its forces on the Ukrainian border by as many as 7,000 troops - despite claims it was withdrawing some soldiers.
A US senior administration official last night blasted Russia's claim it was withdrawing troops from the border with Ukraine. "They received a lot of attention for that claim, both here and around the world. But we now know it was false," the official said.
The anonymous official said "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.
