So @RolandOliphant and I just saw a column of APCs and vehicles with official Russian military plates cross border into Ukraine.

NB I don't think this was "the invasion" proper. This is probably what has been happening for a while. Extraordinary to see it though.

@shaunwalker7 and I just witnessed a not insubstantial column of APCs and trucks slipping across the border into Ukraine.

Didn't even turn off their headlights. Saw Russian military plates on support vehicles, but no markings I could make out on APCs.
