The migrant crisis on Poland’s border, which Western powers accuse Belarusian leader Alexander Lukashenko of engineering, caught international attention in November. But asylum seekers on the Poland-Belarus border aren’t alone in being shunted back and forth across Europe’s land and sea borders, say rights organizations and other monitors.

Throughout the year, irregular migration to Europe has been increasing, with more than 160,000 migrants entering the European Union this year, mostly through the Balkans and Italy. That’s a 70% jump from 2020, when pandemic travel restrictions are thought to have impacted the mobility of would-be migrants, and a 45% increase over the previous pre-pandemic year.

And with irregular migration picking up again, rights campaigners say the EU and national governments are increasingly skirting or breaking international humanitarian laws in their determination to prevent war refugees, asylum seekers and economic migrants from entering or remaining on the continent.

They say European leaders appear determined to avoid a repeat of 2015, when more than a million asylum seekers from the Middle East, sub-Saharan Africa and central Asia arrived in Europe, roiling the continent’s politics and fueling the rise of anti-migrant political parties.

Reports have multiplied of refugees and migrants being forcibly pushed back over the EU’s external borders. So, too, have reports of refugees being prevented from filing asylum applications. Poland passed a law in August stipulating that migrants who cross the border are to be “taken back to the state border” and “ordered to leave the country immediately,” preventing them from making an asylum application.

Pushbacks breach both European human rights laws and the 1951 Geneva Convention, which outline the rights of refugees as well as the legal obligations of the 146 signatory states to protect them.

Signatory states aren’t allowed to impose penalties on refugees who enter their countries illegally in search of asylum, nor are they allowed to expel refugees (without due process). Under the convention, refugees should not be forcibly returned, technically known as “refoul,” to the home countries they fled. Asylum seekers are meant to be provided with free access to courts, and signatory states are required to offer refugees administrative assistance.

The EU, its border agency, Frontex, and the bloc’s national governments, say they do observe international humanitarian law, but according to several recent investigations by rights organizations, the rules are now being flouted routinely and systematically.

“EU member states have adopted increasingly restrictive and punitive asylum rules and are focusing on reducing migration flows, with devastating consequences,” Amnesty International warned recently.

“We are witnessing tremendous human suffering caused by the EU-Turkey deal and by the EU-Libya cooperation, both of which are leaving men, women and children trapped and exposed to suffering and abuse,” the rights organization says in reference to deals struck with Turkey and Libya to block migrants heading to Europe and readmit them when they are ejected from Europe.

In the case of Libya, migrants are often returned to detention camps run by militias where Amnesty International and others have documented harrowing violations, including sexual violence against men, women and children. In a report published earlier this year, Amnesty noted, “Decade-long violations against refugees and migrants continued unabated in Libyan detention centers during the first six months of 2021 despite repeated promises to address them.”

Lighthouse Reports, a Dutch nonprofit journalism consortium, has documented dozens of instances in which Frontex surveillance aircraft were in the vicinity of migrant boats later intercepted by the Libyan Coast Guard. “There is a clear pattern discernible. Boats in distress are spotted, communications take place between European actors and the Libyan Coast Guard,” Lighthouse researchers said in a report this year.

Frontex has routinely denied the allegations but lawmakers in the European Parliament accused the agency, after a four-month investigation, of failing to “fulfill its human rights obligations.” In the Balkans, the Border Violence Monitoring Network and other NGOs say they have gathered testimony from hundreds of refugees who allege they have been beaten back into Bosnia-Herzegovina across the Croatian border by baton-wielding men whose uniforms bear no insignia.

Europe’s peripheral countries have also been erecting border fences and building walls with the prospects of more Afghan refugees appearing on their borders acting as a spur. Greece has completed a 40-kilometer wall along its land border with Turkey and installed an automated surveillance system to try to prevent asylum seekers from reaching Europe. Other countries are following suit and have been pushing the EU to help with funding.

Critics say the wall-building now contrasts with the criticism European leaders leveled four years ago against then-U.S. President Donald Trump over his plan to build a wall on America’s southern border with Mexico. “We have a history and a tradition that we celebrate when walls are brought down and bridges are built,” admonished Federica Mogherini, then the EU’s foreign policy chief.

While migrant advocates complain of rights violations, calls are mounting in Europe for changes to be made to both the Geneva Convention and the bloc’s humanitarian laws. Critics of the convention say it was primarily drawn up to cope with population displacement in Europe in the wake of the Second World War. They say it fails to recognize the nature and scale of the much more complex migration patterns of the 21st century, which could see numbers swell because of climate change.

Last week in Budapest, Balázs Orbán, a deputy minister in the Hungarian government, said the current EU migration laws should be replaced. The current legal system is “catalyzing the influx of illegal migrants, and not helping to stop them on the borders,” he said. “This framework was created during the time of the Geneva Convention in 1951, when refugees from the Soviet Union needed to be accommodated for. Now, times have changed,” he added.
