Poland Interior Minister Mariusz Kaminski declared Monday that in order to reduce migrant inflow from Belarus, the adjoining security borders with Greece and Turkey will be strengthened by structuring a perimeter that would include a system of motion sensors with thermal cameras.

The influx of migrants is rising mostly from countries such as Iraq and Afghanistan. Belarus has been actively helping all migrants cross borders by providing transport facilities. At the end of May, Belarus President Alexander Lukashenko announced that his government would no longer prevent migrants from illegally entering Lithuania through Belarus. President Lukashenko clarified that this active help to the migrants has been provided in retaliation for the EU enacting sanctions to punish Belarus for its treatment of journalists.

Due to the actions of Belarus, Poland and Lithuania have been facing issues as migrants are camping on the borders. The European Court of Human Rights in August decided to apply Article 39 and request that the Polish and Latvian authorities provide all the applicants with food, water, clothing, adequate medical care, and, if possible, temporary shelter. The court also clarified that this measure should not be understood as requiring Poland or Latvia to let the applicants enter their territories.

However, the situation has worsened around the Polish borders. Four people died, and UN High Commissioner for Human Rights Michelle Bachelet told the Human Rights Council in Geneva that she continues to be alarmed by “persistent allegations” of widespread and systematic torture of protestors in Belarus.

Poland previously announced it would build a fence along its border with Belarus, as well as double the number of troops there in order to halt a flow of migrants. This has been multiplied by adding a system of motion sensors with thermal cameras. These security efforts have been criticized by various NGOs and called illegal pushbacks and violations of human rights.
