For many migrants who´ve long dreamed of Europe, one of the last stops is an expanse of olive trees on North Africa’s Mediterranean coastline. But in Tunisia, less than 100 miles (161 kilometers) from the Italian islands that form the European Union´s outermost borders, for many that dream has become a nightmare. Under black tarps covered with blankets and ropes, men, women and children seek shelter from sunlight and wait for their chance to board one of the iron boats that paid smugglers use to transport people to Italy. Having fled war, poverty, climate change or persecution, they find themselves trapped in Tunisia – unable to reach Europe but without money to fund a return home. Based on unofficial estimates, the U.N.´s International Organization for Migration said it believes 15,000 to 20,000 migrants are stranded in rural olive groves near the central Tunisian coastline. Their presence is a byproduct of anti-migration policies being championed in both Tunisia and throughout Europe, particularly from right-wing politicians who are expected to gain ground in the European Union’s parliamentary elections this week. The encampments have grown in size since last year as police have pushed migrants out of cities and ramped up efforts to prevent Mediterranean crossings. When police razed tents last summer in Sfax, Tunisia’s second largest city, many migrants moved to the countryside near the stretch of coastline north of the city. Among them is Mory Keita, a 16-year-old who left a flood-prone suburb outside of Abidjan, Ivory Coast, last September to link up with a friend already in Tunisia. Keita arrived at an encampment called Kilometer-19 earlier this year. Named for a highway marker denoting its distance from Sfax, Kilometer-19 is notorious for clashes between migrant groups, he said. “Machete brawls” regularly break out between groups that self-sort by nationality – including Cameroonians, Ivorians, Guineans and Sudanese. When police come, it´s not to ensure safety, but to disband encampments by force, Keita said. “The truth is I´m afraid of where we are,” he said. “Innocent people get hurt. The police don´t intervene. It´s not normal.” Passportless, Keita said he paid a smuggler an initial sum of 400,000 Central African Francs ($661) to take him through Mali and Algeria last year. He dreams of resettling in France, finding work and sending earnings back to his family in Ivory Coast. Keita made it onto a boat on the Mediterranean Sea in March, but Tunisia’s coast guard intercepted it, arrested him and returned him to the nearby beach without any bureaucratic processing, he said. With European funds and encouragement, the coast guard has successfully prevented more migrants like Keita than ever before from making dangerous journeys across the sea. From January to May, it stopped nearly 53,000 migrants from crossing its maritime border to Europe, Interior Minister Kamel Fekih said last month. Less than 10,000 migrants successfully crossed from Tunisia to Italy this year, down from 23,000 in the same time period last year. That fulfills objectives that European leaders outlined last summer when they brokered a 1 billion euro ($1.1 billion) accord with Tunisia. Though the funds have not been completely disbursed, the deal included 105 million euros ($114 million) for migration-related programs. NGOs such as the Catholic Committee Against Hunger and for Development have decried a lack of transparency and information about the programs. While fewer people landing on the shores of Italy looks like a success, the resulting logjam on the Tunisian coastline is fomenting anger and despair among migrants and Tunisians. Civil society groups have demanded the government expel migrants. Politicians have urged residents to form “citizen militias” to police the area. “You brought them here and it´s your responsibility to send them back to their home countries,” Moamen Salemi, a 63-year old retiree from nearby El Amra, said at one of several recent anti-migrant protests. The U.N. High Commissioner for Human Rights said last month it was “very concerned by the increased targeting in Tunisia of migrants, mostly from south of the Sahara, and individuals and organizations working to assist them.” “We are witnessing a rise in the use of dehumanizing and racist rhetoric against Black migrants and Black Tunisians,” it said in a statement. Though migrants from sub-Saharan Africa have been a political flashpoint, the majority of those who have made it from North Africa to Italy this year have been from either Syria, Bangladesh or Tunisia itself. The government has for more than a year been accused of deporting migrants across its borders with Libya and Algeria, many who are later found dead. Tunisia has acknowledged bussing migrants to the remote borderlands near the two neighboring countries. Yet removing them from areas near the coast does little to answer the anti-migrant anger brewing among residents, many of whom have tried to emigrate to Europe themselves in search of more freedom and better economic opportunities.
