What to know about the arrival of 49,000 migrants into Spain's Ceuta

In the span of 24 hours, Spanish authorities estimate that over 49,000 migrants crossed in Spain from Morocco, with at least 18 dying as they tried to reach the enclave of Ceuta. The migrants crossed the border by swimming across, sometimes spending hours in the water. The arrivals are way over half the population of the enclave.
