The United States has acquired intelligence about a Russian plan to fabricate a pretext for an invasion of Ukraine using a faked video that would build on recent disinformation campaigns, according to senior administration officials and others briefed on the material.

The plan — which the United States hopes to spoil by making public — involves staging and filming a fabricated attack by the Ukrainian military either on Russian territory or against Russian-speaking people in eastern Ukraine.

Russia, the officials said, intended to use the video to accuse Ukraine of "genocide” against Russian-speaking people. It would then use the outrage over the video to justify an attack or have separatist leaders in the Donbass region of eastern Ukraine invite a Russian intervention.
