Fourteen alleged accomplices of the Islamist gunmen who killed 17 people – including four at a kosher supermarket in Paris and 12 at the offices of satirical magazine Charlie Hebdo – are to face trial five years after the attacks.

The defendants, three of whom will be tried in absentia and may be dead, face charges including financing terrorism, membership of a terrorist organisation and supplying weapons to the perpetrators.

The accused are alleged associates of Amedy Coulibaly who murdered three customers and one employee at the Hyper Cacher kosher store in Porte de Vincennes in January 2015.

They are also accused of involvement in the massacre of 12 people at Charlie Hebdo’s offices, led by brothers Said and Cherif Kouachi, a few days earlier.

Charlie Hebdo’s editor Laurent Sourisseau confirmed the publication is to reprint the cartoons of the Prophet Muhammad ahead of the trial in a show of determination in the face of intolerance.

“We will never lie down. We will never give up,” he said of his decision to republish.

Among those charged are Hayat Boumedienne, Coulibaly’s partner at the time of the attacks, and brothers Mohamed and Mehdi Belhoucine. All three travelled to areas of Syria under Islamic State’s control days before the attacks and may be dead.

The trial will run for 10 weeks and be filmed throughout.

More than 250 people have been killed in France in Islamist violence since the attacks and countering the threat remains a government priority, Interior Minister Gerald Darmanin said.

Al Qaeda’s Yemen branch placed Charlie Hebdo’s then-director on its “wanted list” after the weekly published caricatures of the Prophet Mohammad, including one of him in a bomb-shaped turban.
