France is set to build a £337million American-style 'super-max' prison in the heart of the Amazon rainforest that will house drug lords and Islamist terrorists.

The massive 40,700 square meter complex will be build in Saint Laurent du Maroni, in the jungles of French Guiana, said hardline justice minister Gérald Darmanin on Sunday, who visited the region to make the announcement, amid growing fervour against the so-called 'Mexicanization' of France at the hands of violent drugs gangs.

Darmanin told a local outlet that no quarter would be given to those imprisoned at the jail.

'The prison regime will be extremely strict, with one aim: to put the most dangerous narcotraffickers in a place where they can do no harm', he said.

The Saint Laurent du Maroni prison will hold up to 500 prisoners, and will have specialised high-security wings specifically for drug barons and Islamist extremists who posed too high a national security risk to be kept in general population.
