Belarus–European Union border crisis

In August 2021, the government of Belarus began sponsoring an influx of migrants, mostly from the Middle East and North Africa, to the borders of Lithuania, Poland and Latvia. Although Belarus denied involvement, both the European Union and independent observers viewed it as hybrid warfare undertaken in response to the deterioration in Belarus–European Union relations following the 2020 Belarusian presidential election and the 2020–2021 Belarusian protests.
