Residents of the Spanish North African enclave of Ceuta tore down makeshift migrant shelters as police fired rubber bullets during escalating protests over the migration crisis, videos posted online purport to show. Thousands of migrants remain in the territory nearly a month after a record mass crossing from neighboring Morocco, with many seeking asylum in the EU.

The crisis erupted in late July, when around 72,000 people crossed or attempted to cross into Ceuta, many by swimming around border barriers. Most were returned, but Spanish Interior Minister Fernando Grande-Marlaska has said around 5,000 remain. Ceuta President Juan Jesus Vivas has put the figure as high as 9,000.

Thousands of residents took to the streets on Wednesday for a second day of protests, demanding faster deportations and criticizing Madrid’s handling of the crisis. Demonstrators carrying Spanish flags marched toward government buildings chanting “No invasion – expulsion.”

Protesters later headed toward El Trampolin beach, where migrants had erected makeshift shelters. Police intervened to keep the groups apart and fired rubber bullets as tensions escalated, according to media reports. Several shelters were torn down during the confrontation.

The influx has strained the resources of the tiny Spanish territory with a population of roughly 84,000 people, with thousands sleeping on beaches, in forests, and on the streets. Local authorities have struggled to provide accommodation, food, and sanitation while processing asylum claims and determining who can be returned.

Ceuta’s government has accused Madrid of failing to do enough to resolve the crisis. Police cleared about 1,500 migrants from a beach last Thursday and transferred them to temporary facilities, but hundreds reportedly returned within hours amid fears of deportation.

The mass crossing has also left scores of migrants dead. At least 88 bodies recovered following the influx were being buried at Ceuta’s Muslim cemetery last week, with only nine identified, according to media.

Migrants have meanwhile staged their own demonstrations demanding asylum. Around 200 gathered at El Trampolin earlier this month carrying signs reading “We don’t want to return to Morocco” and “We are human too.”

Ceuta, along with Melilla, forms the EU’s only land border with Africa and has long been a destination for migrants seeking to reach Europe. The latest influx was fueled by economic hardship in Morocco and viral claims that Spain had effectively opened its border.

Spanish and Moroccan authorities have blamed smugglers and online misinformation for encouraging the crossings. Morocco has since reinforced security around Ceuta, while Madrid has moved to speed up asylum decisions and the return of migrants with no right to remain.
