Russia’s war against Ukraine has opened a brand-new front for disinformation and influence operations in Europe. A major influx of refugees from Ukraine into neighbouring countries has created opportunities for perpetuating anti-Western narratives, exploited by local nationalist and xenophobic groups. This research is part of the project UKRAINE MONITOR (Monitoring of Networks of Influence Tactics and Operations in the Region), which tries to document these phenomena and disseminate the information to relevant parties in four countries: Romania, Hungary, Poland and Serbia.
