"NATO has observed some continued Russian troop activity in the vicinity of the border with Ukraine over the past days. There is some evidence of equipment and supplies being packed or prepared for movement in certain locations," the officer said.
"The activity we are observing at present could suggest a slow or staged withdrawal of forces. At present, the bulk of the previously deployed Russian force remains in the vicinity of the border," the officer, speaking on condition of anonymity, said.
