Spain and Morocco reinforced the border fence of a Spanish enclave on Friday and appeared to have halted mass crossings, after around 49,000 people arrived by sea and land in a single day, with at least 19 dead bodies found in the water.

Officials estimate that more than 49,000 people crossed between Morocco and Ceuta in a 24-hour period.

The mass crossing into Ceuta caused division in Europe, with Italy threatening to suspend the EU’s internal open border scheme.
