Ukraine’s SBU domestic intelligence service announced Thursday that it had prevented a plot orchestrated by a Russian intelligence service that would have seen Ukrainians travel to Russia to attack Russian interests.

The purported intent of this attack would have been to provide the Kremlin with justification for Russian retaliatory measures against Ukraine. The disrupted plot, if verified, would be in the form of the false-flag “maskirovka,” or “camouflage,” strategy that the United States is concerned Russia is pursuing toward Ukraine.
