In March 2019, three teenage asylum seekers were arrested upon their arrival in Malta. The government charged them with terrorism and alleged that they had hijacked the El Hiblu, a merchant vessel that rescued the three teenagers alongside over one hundred other people, in order to avoid being forcibly returned to Libya. In this chapter, we use the El Hiblu case to examine the ways in which people on the move and activists working in solidarity with them transgress state boundaries and categories to contest EU borders, despite the increasing state criminalization and violence they face. In doing so, they recreate spaces from the Mediterranean to European cities and enact different visions of our societies. The El Hiblu case allows us to explore the ways in which transgressive acts - from autonomous migration to solidarity practices that occur at sea and within European territory - connect and challenge our conceptualization of borders, nation-states, and citizenship.
