The Belarus–Poland migrant crisis consisted of a Belarusian engineered influx of immigrants, mainly from Iraq, to Poland via the border with Belarus. Belarus's dictator Alexander Lukashenko threatened to "flood" the EU with "drugs and migrants". Belarus began fraudulently promoting cheap flights to Belarus from the middle East as an easy way to enter EU borders, as well as assistance in crossing the border for the migrants.
In response to the crisis, Poland adopted harsh deterrence policies, such as mobilising and deploying the military on the border, aggressively pushing back successful entrants into Belarus and finally, building 183km of border wall in popular crossing areas.
