PARIS (AP) — With the Paris Olympic Games 100 days away, police carried out a large-scale eviction at France’s biggest squat in the south of the capital. Authorities, including dozens of gendarmes, cleared out the makeshift camp at an abandoned bus company headquarters in Vitry-sur-Seine on Wednesday.

The camp had become home to about 450 migrants, with images of the eviction spreading rapidly across social media. Aid workers are concerned that the broader effort by Paris authorities to clear out migrants and other people sleeping rough in the capital before the summer Olympics is troubling, as those evicted are not provided longer-term housing assistance.

“The squat was the biggest in France. It doubled in size in one year because of the Olympics. Last year, authorities cleared out migrants from nearby the Olympic Village, and many displaced people came here,” said Paul Alauzy of the humanitarian organization Médecins du Monde, who has been closely following the steady pace of evictions over two years. The conditions inside the warehouse were cramped, Alauzy said.

The clearance operation will continue over several days. The site is currently empty: 150 people left during the night before the police arrived, while 300 were evicted before 8 a.m. Wednesday morning. Among the 450 were 20 children and 50 women, the aid group said.

This action is part of a broader push by local authorities to dismantle makeshift camps as the city prepares to host the Olympics from July 26 to August 11.

Advocacy groups working with the homeless and other vulnerable populations have been voicing their concerns for months. They have been particularly vocal about the accelerated pace of camp clearances as the Games approach, warning of the dire consequences for those who find themselves without shelter.

On Wednesday, observers say some five buses were at the site, intended to transport migrants to specially allocated sites in cities such as Orleans or Bordeaux. Other migrants will be bused to temporary filtering sites. Alauzy said he fears that “it will just be a matter of days or weeks for many of the migrants to be sleeping rough on the street again.”

The fate of these displaced individuals remains a pressing issue as the city gears up for its time in the global spotlight, highlighting the tension between urban beautification efforts and support for marginalized communities.

Earlier this month, French police removed about 50 migrants, including families with young children, from the forecourt of Paris City Hall. The migrants packed their belongings and boarded a bus to temporary government housing in the town of Besançon in eastern France.
