Spain announced it was installing a 500-meter-long (1,600-foot) containment barrier on the sea border between its North African territory of Ceuta and neighboring Morocco after between 50,000 and 60,000 migrants breached the frontier earlier this week.

The death toll climbed to 67, including some who drowned and others who were killed in a stampede to cross a breakwater barrier, the Spanish government said Saturday.

Spanish Prime Minister Pedro Sánchez slammed the reaction of some other European Union leaders to the events in Ceuta, saying calls for Spain to be suspended from the EU’s borderless Schengen zone were “driven by prejudice, fake news, ignorance, or political interest.”
