A French journalist who was held in Syria by ISIS, Nicolas Henin, has come forward claiming that one of his captors was Mehdi Nemmouche, the same man accused of having shot and killed four people at the Brussels Jewish Museum on May 24.

As CNN reported, Henin claims that Nemmouche was one of his guards during the 10 months that he spent captured in Syria. He alleges that Nemmouche beat and tortured him and other Syrian captives.

Henin says that he spent seven months of his time as a hostage with James Foley, the American journalist who was beheaded by ISIS forces around August 19. Henin was unsure if Nemmouche and Foley had any contact with each other.

Henin was released from captivity in April. According to CNN, he claims to have identified Nemmouche as one of his captors by “a number of graphic and audio materials.”

Nemmouche was arrested in Marseille and subsequently extradited to Brussels where he currently faces charges of “murder in a terrorist context” (“Brussels Jewish Museum Gunman Charged“). The 29-year-old Frenchman of Algerian descent is said to have fought in Syria beginning in 2012 before returning to Europe to carry out the attack. 

Three of the victims from the Jewish Museum shooting, a museum employee and two Israeli tourists, died at the scene. The fourth, another museum employee, died at the hospital on June 6th (“Man Shot in Brussels Jewish Museum Attack Dies From Wounds“).
