Why is "2021–2022 Belarus–European Union border crisis" trending?

Wikipedia Overview

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. Between August and December 2021, tens of thousands of unauthorized border crossing attempts were recorded, peaking in October. At least 20 migrants died in the following winter due to the harsh weather and abuse from border authorities. Attempted border crossings fell sharply the following year, but never returned to their pre-crisis levels. In the spring of 2024, numbers began rising again, although they remain well below those seen in the peak of the crisis in 2021.
