Current estimates are some 60,000 people crossed into the Spanish enclave in North Africa on Thursday — and by Friday, that an estimated 48,300 had returned to Morocco. Here's what we know.

Hundreds of migrants from Morocco have swum into the Spanish enclave of Ceuta over the last week.

Around 50,000 migrants crossed into Spain’s North African exclave of Ceuta this week, a mass influx that overwhelmed local authorities. At least 57 people died during the crossings, which prompted tighter border security measures across Europe.

Italy on Friday closed its borders with Spain over the Ceuta migrant crisis, suspending the free movement agreement between the two countries.
