French plans to build a maximum-security prison wing for drug traffickers and Islamic militants near a former penal colony in French Guiana have sparked an outcry among residents and local officials.

The wing would form part of a $450m (£337m) prison announced in 2017 that is expected to be completed by 2028 and hold 500 inmates. The prison would be built in Saint-Laurent-du-Maroni, a town bordering Suriname that once received prisoners shipped by Napoleon III in the 1800s, some of whom were sent to the notorious Devil’s Island off the coast of French Guiana.
