Sid Ahmed Ghlam, 24, was taken into custody on Sunday after he accidentally shot himself in the leg, a fluke occurrence that led to police uncovering an alleged plot to attack at least one church in the town of Villejuif, just south of Paris.
Ghlam, who remains in a Paris hospital recovering from the gunshot wound, was charged with "murder and attempted murder in connection with a terrorist enterprise" and criminal conspiracy, a source close to the case told AFP, adding that he was due to go before a judge on a prosecution request he be remanded into custody.
Police say they found an arsenal of weapons, tactical gear and cellphones in Ghlam's car and student flat, but one of the suspect's lawyers said today he denies "vigorously all the accusations against him." Investigator say they uncovered detailed plans to attack churches and linked Ghlam's DNA to the murder of a young mother in Villejuif who was found shot dead in the passenger seat of her car on Sunday.
He was arrested after he accidentally shot on his leg.
Security sources said the killing may have resulted from an attempt to steal the vehicle of the victim, 32-year-old Aurelie Chatelain. The foiled church plot comes less than four months after the jihadist killing spree on Charlie Hebdo magazine and other targets around Paris that left 17 people dead.
Paris prosecutors have released a 25-year-old woman taken into custody on Wednesday for questioning after investigators discovered encrypted electronic communications between her and Ghlam. Investigators believe the suspect, who had previously drawn the attention of French intelligence agents over his postings on social networks expressing his desire to join jihadists fighting in Syria in 2014, was not acting alone.
"He appeared literally under the heel of" his commanders who told him where and how to get his hands on the kalashnikovs, pistols and bulletproof vests found by police, said a police source.
"This type of individual does not act alone," said Prime Minister Manuel Valls, who evoked "an order... to target a church." Valls said over 1,500 French citizens have been implicated in "terror networks", 442 of whom were currently believed to be in Syria.
