"The war in Ukraine is just the latest instance where attention-grabbing events have fuelled the rapid spread of false or misleading news about refugees and migrants. This Issue Paper examines the challenges posed by disinformation about refugees from Ukraine, as well as the responses taken so far to address it. It inspects which disinformation actors spread false claims about Ukrainian refugees, and how. It sheds light on why migration-related disinformation is so pervasive and how disinformation narratives change over time and space. It also examines which audiences are more susceptible to online disinformation. The paper also identifies positive developments and shortcomings in the EU's responses." (Executive Summary, page 5)
