PARIS (AFP) - French security forces believe they have prevented a terror attack being plotted by two inmates in a French jail, casting a new spotlight Tuesday (Oct 10) on the problem of radicalisation in the country's prisons.
Sources close to the investigation said late Monday that the men were accused of discussing a potential hostage-taking or machine gun attack from their cell at the Fresnes prison south of Paris.
One of the suspects is a 28-year-old from Cameroon described by authorities as an Islamic State in Iraq and Syria (ISIS) sympathiser, while the other is a 22-year-old Frenchman. Both were set to be released this month.
The Cameroonian was believed to have been in contact with a person in Iraq or Syria, where the ISIS's self-proclaimed "caliphate" has lost swathes of territory.
The two had been considering different potential targets such as police or prison guards, a source said on condition of anonymity.
Both were behind bars for non-terror offences and are suspected of being radicalised while serving their sentences. They were charged Friday with being part of a terrorist conspiracy.
The Cameroonian, who was due to be released Tuesday, confirmed to investigators that he was planning on carrying out an attack, a source said.
The Frenchman was due to be released next week.
Terror investigators moved to arrest them after a 44-year-old man from the French island of Reunion in the Indian Ocean, who was in contact with the pair, indicated he was "planning on heading to the mainland to offer them logistical support".
Justice Minister Nicole Belloubet said Tuesday that France urgently needed to stop prisoners from being radicalised behind bars.
"What was revealed yesterday is testament to the urgency of the situation," she told Europe 1 radio.
In August, a radicalised prisoner attacked two guards at the Osny prison north of the capital in what was seen as France's first extremist assault within a jail.
The prisoner, who was behind bars for attempting to travel to militant-held territory in Syria, told investigators he "wanted to kill a prison guard" in the name of ISIS.
France has suffered a string of extemist attacks over the past two years that have left more than 240 people dead.
Some of those responsible were involved in Muslim networks in jail, including Cherif Kouachi, one of the gunmen who attacked satirical magazine Charlie Hebdo in January 2015, and his friend Amedy Coulibaly who killed four at a Jewish supermarket two days later.
Fresnes is one of three French prisons under special watch for radicalisation, where prisoners are assessed for signs of extremism before their arrival.
