Spain braced for Europe's huge annual exodus

ALGECIRAS, Spain - It's the largest annual human migration in Europe: millions of people from France, Belgium and Italy cross Spain every summer to spend their holidays with family in north Africa.

This year, close to 3 million are expected to make the trip there and back through 16 ports in Spain, Morocco and Algeria in an exodus that presents a huge logistical challenge.

In 2016, Spain's civil protection agency registered 2.8 million passengers crossing the country, and it expects more to make the trip this year.
