BARCELONA, Spain (AP) — Hundreds of migrants are swimming from Morocco to the tiny Spanish territory of Ceuta at the country’s northern tip, overwhelming border security, local authorities said Wednesday. While good weather usually brings a surge in migrant crossings by sea in the summer, Ceuta authorities said the current number of swimmers is unusual. “In the last few days, more than 1,500 migrants, including adults and minors, have reached Ceuta by sea,” the leader of Ceuta’s government, Juan Jesús Vivas, told journalists. Spain’s interior ministry, which oversees borders and tracks irregular migration, would not confirm the number of crossings or say how many migrants had reached the territory by swimming. Interior Minister Fernando Grande-Marlaska, in an interview with Spanish television channel laSexta, acknowledged authorities were facing “an extraordinary, exceptional situation.”
