Foiled Islamist Attack Near Pas-de-Calais Prison Uncovered with ISIS Flag and Weapons

French authorities have thwarted a planned Islamist terrorist attack near the Longuenesse prison in Saint-Omer, Pas-de-Calais, leading to the arrest and custody of six men. Among those detained are four individuals, including three inmates with common-law status and one associate from outside the prison linked to an inmate. These suspects face charges including the delivery of illicit objects to inmates, concealment of crimes, and unauthorized aerial surveillance related to the plot.

The investigation intensified after police found a vehicle parked suspiciously close to the prison. A search of this vehicle revealed a loaded handgun, hydrochloric acid, and a flag affiliated with the Islamic State (ISIS/Daech). The two men found in the vehicle were arrested on the spot. Further searches of a relative's home uncovered another handgun, heightening security concerns.

Among the arrested suspects are two brothers born in 2003 and 2005, highlighting a notably young involvement in this foiled attack. Officials have described the seizure of these materials and the collaborative nature of the individuals involved as unprecedented in recent counterterrorism efforts in the region.

This discovery reflects the vigilance of French security forces in preventing attacks on critical infrastructure, particularly penitentiary facilities, which can have wide-reaching consequences. The involvement of inmates in the planned attack and the possession of dangerous materials underline ongoing challenges in maintaining security within and around French prisons.

Authorities continue to investigate the full extent of the plot and any wider networks linked to these individuals. This operation stands as a significant success in French counterterrorism, demonstrating coordinated action to disrupt threats before they materialize.
