A Guardia Civil officer checks the car boot of a Moroccan man driving into Melilla via the Beni Enzar crossing. Entrants to the exclave are searched rigorously for illegal migrants, including the use of heartbeat monitors placed on the cars to check for hidden people. Melilla is a Spanish city on the north coast of Africa, bounded by Morocco and the Mediterranean Sea. Many would-be migrants see it as the gateway to Europe which accounts for the high-level of security along its borders.
